Margin of error of a sample?

2011-11-19T21:04:00.004-08:00

I am so lost! please hellp!!!

A National Retail Foundation survey found households intended to spend an average of $649 during the December holiday season (The Wall Street Journal, December 2, 2002). Assume that the survey included 600 households and that the sample standard deviation was $175.

a. With 95% confidence, what is the margin of error?

b. What is the 95% confidence interval estimate of the population mean?

c. The prior year, the population mean expenditure per household was $632. Discuss the change in holiday season expenditures over the one-year period.

Margin of error of a sample?
n=600

X=649

s175

a. ME is 14.1744

b.637.8256, 663.1744

c. i dont understand what this question is asking

but to find the ME you take a confidence leve of 95% with a degree of freedom of 599 which is aprox. 1.984 then you mulitiply that (1.984) by std dev/sq root of the sample size

so..

1.984 X 175/24.495

for b. you take the mean and ± the ME so 649±14.174

i hope that helps

I want to find the websites which i can find lots of interesting statistical survey!?
The University of Michigan has this page with huge amount of links to data, classified by topic, industry, etc. and includes links to government data as well.

http://www.lib.umich.edu/govdocs/stats.h...

To find several other resources like this, you might be interested in this kind of search at del.icio.us:

http://del.icio.us/search/?all=data%20-v...

This searches for "data" and either "statistics" or "statistical", dropping all matches that included "visualization" (tools)

Del.icio.us is a great tool for doing themed websearching.

In a representative sample. If a music producer conducts a survey around video games and wants to know what college students think of poular music. He conducts the survey in the area of the student union, what is the example of a conclusion the producer might reach based on this survey that might not be true about college students in general

What is an example of a conclusion that a person might reach about this survey described in a representative s
The survey is probably not going to be a simple random sample. The sampling method you are describing would probably best be desribed as a convenience sample. Students who do not frequent the student union would not be represented. If we only ask students who GO to the student union about their thoughts on video games, we won't adequately represent ALL students, including "bookworms" (who are studying in the library) or "commuters" (who go home at night) or "off-campus students". Perhaps we are conducting the survey on a day when there is an impromptu reggae band playing in the student union. We might conclude, then, that ALL college students like reggae music when in fact, the students included in the survey were coming to the student union specifically to SEE the reggae band.

What are the best sites for free stuff/samples?

Preferably ones that are not scam sites. That require a long survey to get a sample.

What are the best sites for free stuff/samples?
I check www.mysavings.com and www.heyitsfree.com just about every day. They troll the web for you, checking for free stuff and gathering it all in one place. Then, all you have to do is click on the links and it takes you straight to the site for the freebie. Uusallly, there is a very short form to fill in, not a survey. The freebies come in anywhere from a few days to 8 weeks. I've gotten skin care samples, razors, toiletries, books, an umbrella, a scarf and more! Have fun!!!

Reply:You can always go to the makeup counters in department stores and ask. They are more than happy to give away freebies because they know if you like a product, you will probably buy it.

Ask what they recommend for your skin and coloring, and when they ask if you want to buy it, say you're not sure, ask if they have samples so you can try it first. I worked at the Lancome counter at Macys...these people work on commission and would be more than happy to let you try it, if you come back its money in their pocket! It certainly doesnt hurt to ask. They will also do your makeup free to try out colors, you just have to book an appointment.
Reply:Chat up salesladies in stores, act sophisticated, maybe buy a little something, then ask for some samples. Works like a charm.

Statistics...survey?

2011-11-19T21:03:00.005-08:00

I'm taking a math statistics class and i have to conduct a survey. I want to know if people lost weight and how did they lose it? How large should my population and sample be? What survey method do you think is best for this survey?

Statistics...survey?
u should also conduct the survey on Y/A and as well as ppl ur friends with! A big sample would be a good idea :)
Reply:In theory, the larger your sample the more reliable your results. In practice, however, this is a school project, so you have to keep it reasonable. Anything in between 10 - 50 people (however much you can manage) should be fine, I guess.

As for the methodology: A fully structured questionnaire; these are really the standard method in quantitative research (which is where statistics are most useful, anyway). A further advantage of this is that you can just give it to people and ask them to fill it out by themselves rather than you having to spend extra time interviewing them.

Make sure to include a demographics section (age, sex, maybe some economic status indicators) so that you can compare these to the overall results.

What would be a good Sports Marketing Research topic (study)? Something that can be researched and tested?

2011-11-19T21:03:00.002-08:00

I'm having a hard time coming up with a good research topic for a class I'm taking in college. I want to do something in the field of Sports Marketing but I am having a hard time thinking of topics that are testable. By testable I mean that these topics need to be tested through surveys, sampling, etc.

Any Ideas?

What would be a good Sports Marketing Research topic (study)? Something that can be researched and tested?
A few ideas:

is there interest in selling assigned seating to games played in a bleacher style gym - some people like the top row where there is some back support; some like front row; others want something else? you could do a survey of people on their way into the gym, find out how much they'd be willing to pay, see if it is a total bomb - just make sure you tell them it is just for your class or you'll have some folks ticked off forever....

find out if there is interest in starting a Bball or hockey or tennis or ??? exhibition match. Like the pre-season BBall tournaments in Hawaii and Alaska (great Alaska shootout). Obviously this might be bigger than you could pull off, but you could find out if there is interest in the topic. Once again, the preseason tourneys recruit student atheletes. A Division II student has little worries about getting on national TV - unless their university has a big tournament that draws division I players - the television of the events on ESPN is what draws good Div. II players to the school - and it helps athletes get exposure.

Smaller items - new surface of an athletic field, roof for it, or build it period..... sold by a marketing idea - an auction for sports related items, dinner made by coach, selling labor of football team members for a day (money goes to team not to player).

hope it helps
Reply:Two ideas. What is the per share profit derived from having an NFL or MLB stadium branded with a corporate name, such as Busch Stadium in St Louis or SAFECO field in Denver.

Or

What is the profit ratio involved with sponsoring a community sports team; such as Bob's barber shop having their name on a little league team uniform. Or is it used as a charitable write off.
Reply:shoes?
Reply:Maybe consider supplements. All athletes take them you could compare and contrast which supplements work best for certain sports but they of course have to be legal. Or you can do the huge industry of soccer which is the most popular sport, Adidas is the #1 soccer brand, I'm also in a marketing class currently, so maybe you could research nike and see how they could boost their revenue by attracting more of the soccer world. Or why adidas is so successful in the sport and why they are actually number 1.

Performed a paired sample t-test but not sure how to interpret the results.?

2011-11-19T21:03:00.001-08:00

I did a 10 question pre %26amp; post survey of the same 10 people. The mean difference is -1.3, Degrees of freedom= 9, standard error of the mean of d= .86, t-statistic for paired data = -1.51, Critical value for alpha .05 would be 2.262.

Now I am not sure how to know whether I accept or reject the null hypothesis. Not even sure what the null hypothesis should be.

My research is whether or not medication improves the school performance of ADHD children. Pre-Survey (before meds) and after survey (while on meds).

I have all these numbers and don't know how to make since of them. Guess I should've paid more attention in that statistics class!

Please help.

Performed a paired sample t-test but not sure how to interpret the results.?
It's very difficult to answer what the null hypothesis should be. If you don't know what you're comparing, then why do the test? I assume you are comparing pre and post test results. Your null hypothesis would most likely be that the test results are the same for both tests. It also sounds like you're preforming a one-sided test on what could be a two-sided test. You would reject any statistic that is above 2.262 or below -2.262 and this would give you an alpha of .05 (.025 on each tail). Basically it looks like you found a two-sided significant value (2.262) but think you're doing a one-sided test. If you're looking to see if there's a significant difference period, then you'd use the two-sided test. If you want to see if the second test scored better, then use the one - sided. (It'd be a lot easier to explain this if I knew exactly how you did the math). If you go above the significant value or below it then you reject the null. Regardless, this won't change your result in this case since your value is -1.51. Basically, any statistic outside of alpha means you reject the null because you have a statistically significant reason to say that the data in the first test is different than the data in the second test. You are making sure there is a significant difference in the data in order to say the medication made a change. Based on your results, you aren't seeing a change since the results. You would not reject the null hypothesis. This means that, based on your results, this drug does not alter test results in patients with ADHD. And yes, you should have paid more attention in statistics class. This stuff really isn't that difficult but you seem so lost. If you plan on doing more of this type of thing I'd suggest taking a stats class again or at least getting a stats textbook and look at it. Also, make sure this is the correct test and that you did it correctly. Based on what you've said, I'm assuming that your resulting t-statistic is correct and that you're using the correct test. It sounds like you have (comparing two results given what it's for) but make sure.
Reply:Based on what you have stated, your null and alternative hypotheses are:

H0: No difference between Pre and Post results.

H1: Post results show better results (medication improves performance)

I presume that the 10 people were the subjects of the experiment and their scores were recorded.

This is a one-tailed test. The critical value at alpha =0.05 is 1.833 (or -2.262 at alpha=0.025). Based on this, the null hypothesis is rejected. That is, medication has improved the subjects' performance.

A school principle wants to survey students to determine whether having internet access at home improves grade

2011-11-19T21:03:00.000-08:00

1.) what type of sample would you suggest

2.) describe a technique for choosing the sample

i need help..... thank you

A school principle wants to survey students to determine whether having internet access at home improves grade
Does the principal have a purpose in mind the answer to the question, "Do students having internet access at home get better (or worse) grades than students without internet access at home get?"

Suppose that the principal believes that grades reflect learning, and he wants an indication of whether he can encourage learning by encouraging students' guardians to provide or deny home internet access to their wards.

Why survey students? The obvious reason is that students are in school and therefore accessible to be surveyed. But they still have to asked, and their answers have then to be tabulated correlated with their grades. But internet access is not a yes or no question. How available is the internet? How convenient is the connection and what is its speed? Dial-up, DSL, or cable? Is there competition from siblings and/or parents for computer time? What about chores, homework, sports, etc.? If a student lives with other students, then the student might be asked to provide information about the internet's home accessibility for those others, as well as for himself.

If the principal wants an indication of how he should guide guardians with whom he speaks about their wards, perhaps he should be surveying those guardians for the accessibility data. A "random" sample of the student body may not be what would be most useful. He could also ask those students and any other of his students sharing the same guardian(s) and compare their answers to check reliability.

But suppose the principal decides to use a representative sample of his entire student body to estimate the correlation of home internet access to grade (improvement) for the whole student body. The problem of sample selection is then how to select a sample that will be representative. Most anyone will tell you that the sample should be "random," but random surveying is more difficult than some people suppose it to be.

The principal could be tempted to go to three of his teachers and ask them to survey all of their students about their internet access, or all of their students of some randomly chosen periods... But it's doubtful that such an approach would yield a random sample. The principal's choice of teachers will be biased in some way. Perhaps he'll exclude coaches, because students don't carry pens to P.E. Perhaps he'll exclude art teachers, because students aren't "serious" in art class.

I suggest that the survey be given to every student. Practically, this means that the whole student body be surveyed at the same time. School absences are not random phenomena, so for rigorously valid results, absent students should be surveyed on their return to school.

If the sample size is to be reduced and remain representative, then some surveys should be selected/eliminated "randomly." For example, if IDs were assigned haphazardly, then the students can be sorted by ID and the survey of every seventh student by this sequence could be considered for the statistical study. Those implementing such a procedure ought to ask whether the effort required to eliminate part of the sample is justified by the reduction in effort required to process the remaining surveys. The answer will depend on details of the process which I cannot evaluate from this distance.

Imagine if only every seventh student by ID were selected to be surveyed. How would the principal collect his data? Would these students be called to a special assembly and interrogated there? If so, their grades might fall because of the classroom time they missed. Surveying the entire population is costly but eliminates sampling error.

Looking for advice on legal preperation for giving out free samples and surveys for a business not open yet?

I want to open a business where I would sell all-natural products for health, beauty, household, and pain management, as well as other things related to herbalism, aromatherapy and other natural health products. I have tested my recipes myself, and family has tested them for me, but I would like to get a table at a health and wellness fair to give surveys about my future business and to give out free samples with my name and number for people to try. I'm trying to find out about any legal preparations I need to make. I don't have a registered business name or anything, I just want to do some research to prepare myself a bit more before I continue on with the process of opening a small business. Any advice would be really appreciated.

Looking for advice on legal preperation for giving out free samples and surveys for a business not open yet?
You shouldn't need to worry about any legalities if you are not selling anything. However if you are selling these things you will need a retail license or a business license. I am a Naturopathic Doctor and I sell herbal meds to people. All I have is my business license. However I would be interested in what products you have to offer. If you could send me some samples I would love to try them out. As I end up ordering a lot of my stuff because I don't have the time to make everything myself dealing with my clientele. I have to much to do because I offer medical information as well as consultations to people in need of my services. You also may want to try nolo law they are a self help legal site. Make a disclaimer stating that you are not a doctor and that you do not claim that these products can cure anything. That will protect you from someone trying to sue you. You make no claims no law suit. Just tell them that they are designed to enhance wellness. Please email me seriously.

Reply:I would suggest talking to a business law attorney. Having a Pre Paid Legal plan makes this as cheap as $26 a month. If you want more information check out the link below.
Reply:I think your best bet would be first to incorporate, so that you could protect personal assets and limit personal liability - otherwise, imagine what could be at stake if someone gets sick, or claims to, from one of your samples.

You should also look into legal advice about drafting a disclaimer containing whether any of your products contain ingredients someone could be allergic to, whether they are approved or not by the FDA, what contraindications might be possible with any specific medications, etc.

Great cross section of society.

From the classy to the trashy.

From the intelligent to the more intelligent.

From the rude, crude %26amp; lewd to the more refined %26amp; respectful.

Sell our country to the Mexicans, wealth-redistributing, burn-the-flag, give all our wealth to some third-world-country Ultra-liberals to Spy-on-your-own-people, suspend as many Bill Of Rights as you can, Big-Business, Big-Government, Big-Brother, war-mongering Ultra-conservatives.

Atheist to agnostic.

Virgin-sacrificing, blood-drinking, God-hating pagan to Born-again, Bible-thumping, pew-jumping, speaking-in-tongues, fundamental Christian.

Anti-sexual, asexual, multi-sexual, metro-sexual, heterosexual, bisexual, trans-sexual.

Yep, they're all here.

Reply:No. Do you want to know why? First off, who is asking? Secondly, there is this pesky margin of error thing. When you watch the news and you see at the bottom in small print, "-1/+1" that is the margin of error. Now if there is a 1 point diffrence in yes or no then that margin of error of -1 or +1 makes the poll or survey worthless. Now polls and surveys can have a margin of error up to 7% or more. Ideal a margin of error should be under 2 with the difference between the yes/no well over the margin of error. Hope that helps. A good college statistics class will bore you to death with all this.

Reply:Even with those posts that you speak of(because it's easy for anyone to create as many accounts as they want to do those rude things), I like to think that there's a pretty regular sample of society here, sure. The one thing I've noticed though, especially through yahoo 360, is that there seem to be a lot of people here that are writers, artists, dreamers....just more creative people in general. I don't know if that's a coincidence or if it's because people find it easier to be themselves here, but that's what I've observed. There are all kinds of amazing people here :)
Reply:Unfortunately , yes buddy! People here come from all walks of life , all ages, any lifestyle, and most of all any IQ!

Reply:Not necessarily...There was a telephone poll done in the 1940's to predict a presidential election and the poll was all wrong...the reason was...only a certain kind of people owned telephones...usually more wealthy, more educated and more urban.

I think the same thing is true of computer owners and operators...usually it will be wealthy, educated, urban and most of all BORED. The other thing about computer users is I think many of them are younger than the general population.

We have a large sampling of very young, bored and yet somewhat wealthy (compared to world standards anyway) and intellectual, older people. However, the intellectual, older people can usually find something better to do that work YA for opinions.

You question is sort of like saying "Are people who read dime novels and watch soap operas a good sampling of society?" Not really. The sampling is a little skewed for obvious reasons. I wouldn't trust YA to predict a presidential election but does take a cut out of the middle of society.

Advantege of sampling in any Survey?

2011-11-19T21:02:00.000-08:00

Time and cost.

There is not enough man hours available to survey everyone...and not everyone will give you a response.

Advantege of sampling in any Survey?
Cost.

It is cost prohibitive to survey everyone in the population to get their opinion or find out some attribute about them. If we want to know if Americans agree with some point or another, we can't afford the time and cost to talk to over 200 million Americans. So, by sampling, say, 1000 people, you can get a "good enough" answer without talking to everyone.

This is usually accomplished by either a pure random sample or a stratified random sample. A stratified random sample for a survey might use "strata" to ensure that people of all age groups, gender, and socio-economic status are surveyed in proportion to their occurance in the population and not concentrated into those that might happen to be at home when the survey was performed. For instance, a pure random sample conducted during the day might bias toward the unemployed and stay at home moms and be less likely to include employed people.

These samples will have an "error" associated with them. This might be expressed as 51% of Americans agree with such and such, +/- 1%. This error is the "standard error" and is an estimate of how different the answer would be if you conducted the survey again with a different random sample of people.

Let's say we want to cut the error in half. So we now know the answer that 51% of Americans agree, +/- 0.5%. One aspect of sampling is the central limit theorem and it tells us that to cut the error in half requires a sample that is four (4) times larger, hence four times costly.

I need to do a survey regarding ice cream shops for my business class. Only takes 90 seconds…Please?

2011-11-19T21:01:00.006-08:00

It’s for a school project so the more answers the better. Easy points.

If you’ve done this one already, I need a “larger sampling,” and the questions have changed just slightly. If you do fill it out again (which I have no problem with) just don’t tell me ;)

Which do you prefer and why? Coldstone, Maggie Moo’s or Marble Slab?

Do you prefer a place that offers Mix-ins over one that doesn’t? (Ex. Baskin Robbins, Dairy Queen, etc.)

2011-11-19T21:01:00.005-08:00

A survey claims that 9 out of 10 doctors recommend aspirin for their patients with headaches. To test this claim against the alternative that the actual proportion of doctors who recommend aspirin is less than 0.90, a random sample of 100 doctors results in 83 who indicate that they recommend aspirin. The value of the test statistic in this problem is approximately equal to:

a. -4.12

b. -2.33

c. -1.86

d. -0.07

A survey claims that 9 out of 10 doctors recommend aspirin for their patients with headaches. To test this cla
E(X) = mean = 100*0.9 = 90

Variance(X) = 100*0.9*(1-0.9) = 9

std. deviation = square root of variance = 3

Z = (X - mean) / standard deviation

Z = (83-90)/3 = -7/3 = -2.33

How do sample population studies equate to accurate statistics?

2011-11-19T21:01:00.001-08:00

If it's a sample but not the whole population that's being studied/surveyed/polled, then the truth will never be known. How can a sample tell us about the entire planet?

How do sample population studies equate to accurate statistics?
They can't and don't. You're right statistics are not very dependable... you know that old saying numbers don't lie? But in reality they can, and they do. It's easy to manipulate numbers to get them to say what you want. Example the ratio toothpaste commercials use 2 out of 3 dentists recommend this. But if you put that ratio on a scale of millions it would be like 1 million dentist do not recommend this brand... and I'm not sure if that's a number I'm comfortable with. And percentages vs. fractions: Percentages always sound better because the numbers are generally smaller. Example, why say 1.4 million people in North America has aids, when it sounds less horrifying just to say 0.8%? And those numbers are completely true... But I hope you get what I'm saying. And people use numbers from biased sites. If one person gets a set of statistics from one site to 'prove' something another can get a set to ‘prove’ the exact opposite. And it is simply impossible to get an accurate reason for a whole population from just surveying a fraction of the people. That's how we get numbers that prove both sides of an argument absolutely right... and that's bad.
Reply:a sample population isnt meant to tell you about the entire plannet, its meant to tell you about a particular community about a particular subject. Like, if there are 1000 english professors in a department, you are not going to be able to question all of them, you take a sample of say 250 and ask them a question about what they teach in english class, and you get to see a window of what the rest might teach.

When a sample was surveyed on their preference for yogurt flavor, 12 said vanilla, and 8 said banana,the?
ok.....

1st part: the percentage of those who chose vanilla would be 60%

2nd part: about 100 chose vanilla......

reasoning....

12 +8=20

12 out of 20 people is like wut 55% about

so for the first answer 60% is closest

second answer.... 100 is closest to 60% of 160 people. (64 is less than 1/3 so not even close to the 60%)

Dear Raymond,

Your pertinent question and urgent curiosity has unfortunately, been buried under more legitimate concerns. If you don't get an answer within 24 hours, it is best to delete your query and ask again.

Raymond, I would like to take this opportunity to express my personal opinion. You have been foolish, Raymond. Very, very foolish. Anyone can see that the purpose of Yahoo! Answers is to serve as a modern chatroom. More and more, Java programming is becoming less and less supported, there is no other method of bringing people together in a social environment than to create PHP scripts where the "thinking" can be done on the server rather than on your machine. With that in mind, Raymond, you should interrogate the shallow-minded participants of Yahoo! Answers with matters that appeal to their common denominator. Questions such as, "How long is the normal tally whacker?" or, "My boyfriend says I should dump my hubby, what you think?"..., would get you a substantial number of replies.

Give up your pursuit of truth and petty wonders, Raymond. Quit asking bland, colorless questions. Are you naive? No person who is capable of giving you the answer you hoped for can last while reading though a heap of puddings, pies and pastry. I'm only doing you a favor, Raymond, by giving you a proper admonishment you can now begin to formulate an apology. When you are ready, send your atonement to http://surveys.yahoo.com/user_ad_feedbac...

And Raymond, if you insist upon asking serious questions, remember that a few good jolts from a peace officer's tazor should bring you around to your senses. Please, check your spelling and throw some slang into the mix so you don't offend any of the egos lurking, waiting to pounce on you with crass, thoughtless one-liners.

Thank you Raymond, and have a great day!

Draw a diagram like this one:

http://i26.tinypic.com/2pt2erm.gif

I've labeled each section with the number of students in that section. For example, 19+x students wrote P only.

We also know that 26 wrote Q only, so from the diagram we have

22 + x = 26

So x = 4

Target - Kids

Method - Watch them eat it :)
Reply:Welcome Ben, professor or student? You need not use a calculator or even more than a pencil and paper. Go to your local grocer and watch what they buy and ask is this your favorite. They might be buying for someone else. But, at the end of the day ice cream makers have done this based on sales, the winner believe it or not is vanilla. Mine is always chocolate.
Reply:I wouldn't bother. The ice cream industry has already done this a number of times over the years. They have found that plain vanilla always comes in first place, although in some surveys (like this one: http://gourmetfood.about.com/b/2006/07/0... ) chocolate comes in first (15% for chocolate, 12% for vanilla). Google "favorite ice cream" for lots of web sites about it.

What kind of questions should I ask on a survey, to determine if color affects peoples moods?

2011-11-19T20:59:00.002-08:00

Im conducting an experiment, and I have almost everything I need in order to complete my experiment, but I also want to ask a survey to see if the questions I ask effect the answer of the person give according to the paper. I've researched for sample questions I can ask but im still having a lot of trouble.. can anyone offer some good advice for questions.. I would appreciate it greatly..

What kind of questions should I ask on a survey, to determine if color affects peoples moods?
If you are able to determine someone's mood from answers they give (Ex. "Do you normally visit the movies alone, yes/no why? Yes because I am a loner." You could probably guess they're depressed) then you can make the questions whatever color you like (as in the actual words in the question you would make yellow or whatever instead of the default black). So for the example question you could make it blue to see if you get alot of depressed answers.

You could also make all the questions someone gets one color and then give another person all their questions in a different color.

per week. To avoid having a biased sample, you decide to?

A.include the same proportion of males as females as found in the student population as a whole.

B.servey students who are members of fraternaties and sororities and none from the academic clubs

C.have members of local law enforcement administer the survey to the students

D.post your survey on the college web site to ensure a representative sample of the college population.

B-would not be representative. C-Law enforcement may encourage people to lie. D-People may not visit the college website for a reason or another.
Reply:A. would be the most representative, B would be the most disproportionate but could be worked in tandem with A if you factored in the % of male/female students who belong to social clubs, likewise for academic clubs.

The A still has it for simplicity.

4)A big pharmaceutical company conducted an initial survey to determine the chemical properties of few types?

2011-11-19T20:58:00.002-08:00

4)A big pharmaceutical company conducted an initial survey to determine the chemical properties of few types of Verbena sp., a medicinal plant used by traditional doctors in parts of Argentina. Leaf samples were collected from thirty plants in each of three large populations for analysis in the lab. A fourth, small population was sampled as well, but as only 15 individuals could be easily located, the sample for this population consisted of two samples from separate branches of each of the 15 individuals. The sample from each plant/branch was placed in a labeled bag. While preparing the samples for chemical analysis in the lab, the lab technician found that six of the sampling bags had no labeling. However, as all the sampling bags were stacked in the order in which they were collected, the technician assigned each of the unlabeled sampling bags to a population by its location in the stack. The data were analyzed using a one-way ANOVA test to test the hypothesis that the levels of tannins didn’t differ among Verbena types.

a.Based on the information provided above, which of the assumptions of ANOVA may have been violated? Justify your answer.

b.Can you use the data (or parts of it) to test the research hypothesis in a way that will avoid the violation of this/these assumptions? If yes, please specify how.

For each situation,would you suggest sample survey or census to be conducted? Explain

a) A car manufacter wants to find out if Canadian familes with young children a minifan to a SUV as the family car.

b) A district school board wants to know how many students who are in grade 10 math achiv scores over 90%

Census or Sample ?
a) "survey" can provide highly reliable estimates from a (surprisingly) low number of candidates.

b) "census" of precisely how many students so that school board can provide documentation of achievement to regulators, parents and students. Commencement excercises for example list student names who have achieved academic high scores.

Are attitudes toward shopping changing? Sample surveys show that fewer people enjoy shopping than in the past. A recent survey asked a nationwide random sample of 2490 adults if they agreed or disagreed that "I like buying new clothes, but shopping is often frustrating and time-consuming." The population that the poll wants to draw conclusions about is all U.S. residents aged 18 and over. Suppose that in fact 63% of all adult U.S. residents would say "Agree" if asked the same questions. What is the probability that 1558 or more of the sample agree?

Please help me answer this Statistics question.?
Let Xb be the shoppers who say "agree". Xb has the binomial distribution with n = 2490 trials and success probability p = 0.63

In general, if X has the binomial distribution with n trials and a success probability of p then

P[Xb = x] = n!/(x!(n-x)!) * p^x * (1-p)^(n-x)

for values of x = 0, 1, 2, ..., n

P[Xb = x] = 0 for any other value of x.

To use the normal approximation to the binomial you must first validate that you have more than 10 expected successes and 10 expected failures. In other words, you need to have n * p %26gt; 10 and n * (1-p) %26gt; 10.

Some authors will say you only need 5 expected successes and 5 expected failures to use this approximation. If you are working towards the center of the distribution then this condition should be sufficient. However, the approximations in the tails of the distribution will be weaker especially if the success probability is low or high. Using 10 expected successes and 10 expected failures is a more conservative approach but will allow for better approximations especially when p is small or p is large.

In this case you have:

n * p = 2490 * 0.63 = 1568.7 expected success

n * (1 - p) = 2490 * 0.37 = 921.3 expected failures

We have checked and confirmed that there are enough expected successes and expected failures. Now we can move on to the rest of the work.

If Xb ~ Binomial(n, p) then we can approximate probabilities using the normal distribution where Xn is normal with mean μ = n * p, variance σ² = n * p * (1-p), and standard deviation σ

Xb ~ Binomial(n = 2490 , p = 0.63 )

Xn ~ Normal( μ = 1568.7 , σ² = 580.419 )

Xn ~ Normal( μ = 1568.7 , σ = 24.09189 )

I have noted two different notations for the Normal distribution, one using the variance and one using the standard deviation. In most textbooks and in most of the literature, the parameters used to denote the Normal distribution are the mean and the variance. In most software programs, the standard notation is to use the mean and the standard deviation.

The probabilities are approximated using a continuity correction. We need to use a continuity correction because we are estimating discrete probabilities with a continuous distribution. The best way to make sure you use the correct continuity correction is to draw out a small histogram of the binomial distribution and shade in the values you need. The continuity correction accounts for the area of the boxes that would be missing or would be extra under the normal curve.

P( Xb %26lt; x) ≈ P( Xn %26lt; (x - 0.5) )

P( Xb %26gt; x) ≈ P( Xn %26gt; (x + 0.5) )

P( Xb ≤ x) ≈ P( Xn ≤ (x + 0.5) )

P( Xb ≥ x) ≈ P( Xn ≥ (x - 0.5) )

P( Xb = x) ≈ P( (x - 0.5) %26lt; Xn %26lt; (x + 0.5) )

P( a ≤ Xb ≤ b ) ≈ P( (a - 0.5) %26lt; Xn %26lt; (b + 0.5) )

P( a ≤ Xb %26lt; b ) ≈ P( (a - 0.5) %26lt; Xn %26lt; (b - 0.5) )

P( a %26lt; Xb ≤ b ) ≈ P( (a + 0.5) %26lt; Xn %26lt; (b + 0.5) )

P( a %26lt; Xb %26lt; b ) ≈ P( (a + 0.5) %26lt; Xn %26lt; (b - 0.5) )

In the work that follows Xb has the binomial distribution, Xn has the normal distribution and Z has the standard normal distribution.

Remember that for any normal random variable Xn, you can transform it into standard units via: Z = (Xn - μ ) / σ

P( Xb ≥ 1558 ) =

2490

∑ P(Xb = x) = 0.679494

x = 1558

≈ P( Xn ≥ 1557.5 )

= P( Z ≥ ( 1557.5 - 1568.7 ) / 24.09189 )

= P( Z ≥ -0.4648868 )

= 0.6789937

Toyota provides an option of a sunroof and side air bag package in its Corolla model; this package costs $1400 ($1159 invoice price). Assume that prior to offering this option package, Toyota wants to determine the percentage of Corolla buyers who would pay $1400 extra for the sunroof and side air bag. How many Corolla buyers must be surveyed if we want to be 95% confident that the sample percentage is within 4 percentage points of the true percentage for all Corolla buyers.

Can anyone help solve this problem?

Does anyone know how to solve this statistics problem?
The answer will vary, depending on the test that Toyota uses in the determination. However, for each of the tests, there is a table to determine population versus confidence level. My stat books are packed or I'd be able to give you a more definite answer.
Reply:large sample confidence intervals are used to find a region in which we are 100 (1-α)% confident the true value of the parameter is in the interval.

For large sample confidence intervals for the proportion in this situation you have:

pHat ± z * sqrt( (pHat * (1-pHat)) / n)

where pHat is the sample proportion

z is the zscore for having α% of the data in the tails, i.e., P( |Z| %26gt; z) = α

n is the sample size

in this question we are only concerned with the error term and the width of the interval w.

z * sqrt( (pHat * (1-pHat)) / n) = w

n = pHat * (1 - pHat) (w/z) ^ -2

We have no information on pHat so we will use the value of 1/2. this maximizes the value and if n is sufficient fo p = 0.5, n will be sufficient for all other values of p.

the z-score for a 95% confidence interval is 1.96

n = 0.5 * (1 - 0.5) * (0.04 / 1.96) ^ -2

n = 600.25

n must be integer valued. Always take the ceiling to make sure the size of the interval is correct.

n = 601.
Reply:We need to know the standard deviation of buyers who would pay $1,400 extra to answer this question.

The formula is:

n=[1.96*sd/error]^2

error=4

1.96 comes from the 95 % confidence level and normal distribution assumption. Plug the standard deviation into the equation to find the required sample size.

A recent survey indicated that a person living in the United States consumes approximately 99 pounds of beef per year with a standard deviation of 16.9 pounds. If a sample of 100 persons living in the U.S. is selected at random, what is the probability that the average beef consumption of this sample is between 95 and 105 pounds?

a. 0.0379

b. 0.1181

c. 0.2323

d. 0.4296

e. 0.7140

f. 0.9908

g. none of these

What is a solution to this problem below?
I found (c) 0.2323 to be the answer.

Since I'm guessing you're unsure of how to solve this, use your calculator, assuming you have a TI-83, and go to 2nd VARS. Enter normalcdf(95,105,99,16.9)--you are plugging in the minimum, max, mean, and std. deviation values and you get (c). This should be correct.

I'm stuck on a homework question.?

2010-05-24T03:01:00.002-07:00

A hospital administrator wants to estimate the number of hours worked each day by the nurses in his hospital. The female nurses and male nurses make up 65% and 35% of the nurses working in his hospital, respectively. He randomly selects 50 female and 50 male nurses for his sample survey. So what is the population if interest?What type of sampling method was attemted? Will the sample be representative of the population and prodce a valid result?

I'm stuck on a homework question.?
The population is all the nurses in the hospital.

It looks like simple random sampling was used. As he is only interested in the number of hours worked by nurses each day, the male-female percentage matters and need not have been used. He should have ignored dividing the sexes while sampling as he is not interested in male-female comparison. Rather, he wishes to estimate the number of hours worked each day by nurses. This division may produce a bias if there are differences in working hours between the male and female nurses.

Sample size question?

2010-05-24T03:01:00.001-07:00

several surveys have been done in area towns to estimate the % of people who vote in favor of a tax levy to suport schools. the fraction who say they would vote yes has been estimated at .4 calculate the sample size needed to obtain a 95% confidence interval with a margin of error of plus or minus .04.

Sample size question?
Confidence intervals are used to find a region in which we are 100 * ( 1 - α )% confident the true value of the parameter is in the interval.

For large sample confidence intervals about the population proportion you have:

pHat ± z * sqrt(phat * (1- phat) / n)

where phat is the sample proportion

z is the zscore for having α% of the data in the tails, i.e., P( |Z| %26gt; z) = α

n is the sample size

To find the sample size needed for a confidence interval of a given size we need only to concern ourselves with the error term and the width of the interval.

We know that the interval is centered at phat so we need to find the value of n such that

z * sqrt(phat * (1-phat) / n) = width.

The z-score for a 0.95 confidence interval is the value of z such that 0.025 is in each tail of the distribution.

z= 1.959964

The equation we need to solve is: z * sqrt(phat * (1-phat) / n) = width

n = phat * (1 - phat) * (width / z) ^ -2.

If we don't know anything about phat and are still asked to find the sample size we let phat = 0.5. This maximizes the value of the error term and if n is sufficient for phat = 0.5, the n will be sufficient for all other values of phat.

n = 0.4 * ( 1 - 0.4 ) * ( 0.04 / 1.959964 ) ^ -2

n = 576.2188

n must be integer valued. Always take the ceiling of n so that the size of the interval will be correct.

n = 577

Stastics Question- Please help Statistics Genius...Confidence level of sample proportion....?

Spalding Corp wants to est. the proportion of golfers who are left handed. How many golfers must be surveyed if we want 99% confidence that the sample prop. has a margin of error of 0.035?

A.)Assume-there is no avail. info. that could be used as an est. of the sample prop.

B.) Assume that we have an est. of the sample prop. from a prev. study that suggests 17% of golfers are lefties.

C.)Assume-instead of using randomly selected golfers, the sample data are obtained by asking tv viewers of the golf channel to call an 800 # to report whether they are left or right handed. How are the results affected?

Stastics Question- Please help Statistics Genius...Confidence level of sample proportion....?
Confidence intervals are used to find a region in which we are 100 * ( 1 - α )% confident the true value of the parameter is in the interval.

For large sample confidence intervals about the population proportion you have:

pHat ± z * sqrt(phat * (1- phat) / n)

where phat is the sample proportion

z is the zscore for having α% of the data in the tails, i.e., P( |Z| %26gt; z) = α

n is the sample size

To find the sample size needed for a confidence interval of a given size we need only to concern ourselves with the error term and the width of the interval.

We know that the interval is centered at phat so we need to find the value of n such that

z * sqrt(phat * (1-phat) / n) = width.

The z-score for a 0.99 confidence interval is the value of z such that 0.005 is in each tail of the distribution.

z= 2.575829

The equation we need to solve is: z * sqrt(phat * (1-phat) / n) = width

n = phat * (1 - phat) * (width / z) ^ -2.

If we don't know anything about phat and are still asked to find the sample size we let phat = 0.5. This maximizes the value of the error term and if n is sufficient for phat = 0.5, the n will be sufficient for all other values of phat.

n = 0.5 * ( 1 - 0.5 ) * ( 0.035 / 2.575829 ) ^ -2

n = 1354.061

n must be integer valued. Always take the ceiling of n so that the size of the interval will be correct.

n = 1355

B)

n = 0.17 * ( 1 - 0.17 ) * ( 0.035 / 2.575829 ) ^ -2

n = 764.2318

n must be integer valued. Always take the ceiling of n so that the size of the interval will be correct.

n = 765

C)

since we are only looking at the left/right handedness of the golfer, it is likely that the phone in will not matter to much as there is likely no confounding variable between the ability to phone or the interest in phoning and handedness.

Standard deviation, confidence intervals, basic....?

2010-05-24T03:00:00.000-07:00

I would like to learn about standard deviation and confidence interval. I am very bad at math and alergic to equations. Would you kindly explain in a very simple way why they are necessary when one conducts a sample survey... Grateful for your help! I am desperate....

Standard deviation, confidence intervals, basic....?
Without equations it is going ot be hard to be precise but:

Basically, when you take a sample, the mean (average) of your sample will be close to the "true" mean of the whole population. It will be closer if the sample size is larger. (Central Limit Theorem!) Confidence intervals allow you to say, with some amount of confidence: "I believe that the true value (mu) is in the interval between ...." the two numbers that come out of the formulas.

Compute a 95% confidence interval for the mean family expenditure?

2010-05-24T02:59:00.000-07:00

Expenditure on one category of food is estimated on the basis of a family expenditure survey. The amounts spent are surpassed to vary around an unknown mean, with a standard deviation of 6 dollars. For a sample of 80 families, the average expenditure is 43 dollars.

a) Compute a 95% confidence interval for the mean family expenditure?

b) How large of a sample is required to estimated the mean expenditure to within 50 cents?

c) Do we need to assume that the individual expenditure follow a normal distribution?

Compute a 95% confidence interval for the mean family expenditure?
In this case n = 80, x-bar = 43, s = 6

Standard error of the mean = 6 /√80 = 0.67

The 95% confidence interval = (μ - 1.96 x SE) - (μ + 1.96 x SE), and 1.96 x 0.67 = 1.32

Hence (43 - 1.32) %26lt; μ %26lt; (43 + 1.32), i.e. 41.68 %26lt; μ %26lt; 44.32

b. (This corrects an error in my original answer to this question.)

To get an estimate to within 50 cents with a 95% confidence interval it is necessary to apply the z-value as determined above to the standard error of the mean.

In other words, we require that 1.96 x 6 / √n = 0.5

So √n = (1.96 x 6) / 0.5 = 23.52 or n = 553

So with the same sample mean, for example, this would give the confidence interval as

42.50 %26lt; μ %26lt; 43.50

--------------------------------------...

c. No. The sample means are normally distributed in all cases, irrespective of the shape of the population distribution.

Choose Your Study Purpose

Give an example of a question about high school students, their behavior, or their opinions that would best be answered by

(a) A sample survey

(b) An observational study that is not a sample survey

(c) An experiment

Can someone help me with this?
(a) How many 10th graders are sexually active?

(b) Are teens more likely to be involved in car crashes than experienced drivers?

(c) Would teens do better in high school if school started at 9am?

The last two were actually done and I included links to their pages.
Reply:If you are asking what is a good question, ask what percentage of high school students paticipate in some sort of sport and ask kids from around your school if they do as a sample survery. If you are asking the difference: Sample Survey is a small survey of high school students about some question concerning their opinion behavior, or about them. An observational study is the same except that you don't ask them a question, you observe certain behavior, like how many high school kids are dating. An experiment would be like, well I don't know how to apply this for this question really...

Stats Survey Analysis?

2010-05-24T02:58:00.002-07:00

Hi, my group recently surveyed high school students on their opinions of different sexual orientations. We categorized the students into four categories: ninth, tenth, eleventh, and twelfth. There are five possible choices: Strongly Agree, Agree, Neutral, Disagree, and Strongly Disagree. I decided to make SA worth 5 points, A worth 4 points, N worth 3 points, D worth 2 points, and SD worth 1 point. I multiplied it all out, added it up, and divided by the sample size to find the average response for each grade level. However, I don't know what tests to do to find whether there is a significant difference between genders. I tried doing a 2 Sample T Test but I don't know how to find the standard deviation out of five categories. I don't understand how a Chi-Square would work. Thanks for you time.

Stats Survey Analysis?
I work with stats a lot in my work. Not to be discouraging, but Are you in high school yourself? Or a college student without a lot of experience with stats?

I don't think you have a lot of experience with these tests (since you are not familiar with calculating standard deviations). There are a lot of statistical errors that can be made without training, and you really need one or two post secondary courses to become familiar with inferential statistics.

It would be better to look at the numbers or percentages of males and females who answered with each answer choice) (SA, A, N etc). Put the percentages into a 5x2 table, answer choice in each row and gender in the columns.

If you don't have to do stats, look over the table of percentages, and see it the percentages of males and females at each level are different.

If you decide to do a statistical test, the chi-square is more appropriate. If you have never done this test, get some advice, and use software.

The problem with averaging the answer choices for each gender is that you don't know whether the difference between SA and A, for example, is the same as the difference between N and D, and so on. If it is, a t-test may be OK, but there are other issues relating to the distribtion of data that have to be considered. There is also the possibility of using a non-parametric test based on differences in the ranking of scores between the genders.
Reply:A chi-square test for independence (A.K.A. contingency table) is the appropriate statistical test. It's not that difficult:

1. Draw a 2x4 grid with your four categories as columns and gender as rows. Enter your integer totals in the appropriate cells.

2. Find the total of each row and each column. Write the grand total in the lower right. Check -- the grand total is column totals = the row totals.

3. Find the expected value for each cell by multiplying that row total by that column total and divide each by the grand total.

4. Find the chi-square value for the table by subtracting the expected value from the cell value (your data). Square this difference and divide by the expected value. Do this for each cell.

5. Add all these values. You should have 8 values. This is your calculated chi-square value.

6. Now for the statistical test. Your critical chi-square value is found in any chi-square table in the back of a statistics book. Decide on your α-risk, say α = 0.05.

Your degrees of freedom is (rows - 1)(cols- 1) = 3. So your critical chi-square value is 7.815.

7. Compare this with your calculated chi-square value. If your calculated value is larger, then the hypothesis of independence cannot be accepted and you have significant differences.

But where are these differences, if they exist? Use some of the previous suggestions to find these. But you can now attach a statistical confidence to your results. If you're still confused, look in a statistical text under contingency table. You will find examples.
Reply:I agree with overanxious that if you're worried about a standard deviation, you might be in trouble. Also, by the way you've worded your question, I'm not sure the s.d. you're worried about is an interesting one.

Ignoring whether you will correctly be able to interpret your results, ExCEL can probably do the analysis you want with a single operation. Under tools%26gt;data analysis (an add-in if you don't see it already) %26gt; ANOVA-Single Factor, you can test for differences in means. Excel wants each of your interesting groups in a seperate column, so you'll need to organize your data.

Interesting questions to ask might be, are there differences across grades? Put each grade in a different column (labels at the top, and ask for them in the ANOVA window) and highlight the whole block of data. The F-test tests if there are any differences (it will not tell you where the significant differences are).

You could ask for differences between genders... use a column for each gender. This uses an F-test for the same hypothesis as a simple t-test with a pooled s.d. (p-values will be the same).

You could ask for differences between genders within a single grade... same thing with only part of the data.

You could ask if there are any gender differences in ANY grade... this is a two factor ANOVA table (with replication), and the data organization is a little more complicated.

Do you get statistics?

2010-05-24T02:57:00.001-07:00

A Sample survey interviews an SRS of 267 women. Suppose 70%of women have dieted over the past 12 months. What is the probability that 75% or more of the women in the sample have been on a diet?

I am really confused and would really appreciate any help you can give me. And any tips to understanding statistics in general would be greatly appreciated.

Thanks!

Do you get statistics?
An essential piece of solving this puzzle is knowing the standard deviation associated with the number of women who have dieted (assuming the number of women who dieted is distributed normally). Low standard deviation means the sample is unlikely to deviate from the 70% mean. So, for example, if the standard deviation is high then the probability that 75% of the women in the sample have been on a diet will be large as compared to if the standard deviation is low.

According to Wikipedia: "Standard deviation may serve as a measure of uncertainty. In physical science for example, the reported standard deviation of a group of repeated measurements should give the precision of those measurements. When deciding whether measurements agree with a theoretical prediction, the standard deviation of those measurements is of crucial importance: if the mean of the measurements is too far away from the prediction (with the distance measured in standard deviations), then we consider the measurements as contradicting the prediction. This makes sense since they fall outside the range of values that could reasonably be expected to occur if the prediction were correct and the standard deviation appropriately quantified."

7. You interview every thent person leaving each voting place in your school district.

Those were the questions. i need help!!!!!

7 would be the most accurate way but it is not very practical. It's not 5 because you would only be surveying people interested in computers. It's either 6 or 7. I pick 6. If it's wrong then argue with the teacher :)

I need to print out a sample of a DRA (Developmental Reading Assessment). The teacher wants me to test a student by doing a Phonics Mastery Survey and a Fluency Evaluation. I'm already working w/ a 1st grader but my teacher is very vague and I'm not asking her any questions! I'm better off finding it in the internet! But , where can I print free online samples of these test? I need them for tomorrow, June 2nd!

Pearson does not provide samples on the Internet. But, most schools have several kits. Go to the elementary school that you attended and ask one of your favorite teachers to make a copy. Or, ask the teacher of the first grader you are working with. Good luck!

2010-05-24T02:56:00.000-07:00

A nationwide survey claimed that at least 65% of parents with young children condone spanking their child as a regular form of punishment. In a random sample of 100 parents with young children, how many would need to say that they condone spanking as a form of punishment in order to refute the claim at alpha=0.5?

a)you would need exactly 57 parents to support spanking to refute the claim

b) you would need 57 or less parents to support spanking to refute the claim

c) you would need more than 57 parents to support spanking to refute the claim

d) you would need 58 or less parents to support to refute the claim.

A nationwide survey claimed that at least 65% of parents with young children condone spanking their child as a
the alpha level of 0.5 is not a realistic value. the value of 0.05 is much more probable.

to refute the clam the test statistic needs to be less than -1.645

the test statistic is z = (phat - 0.65) / sqrt( 0.65 * (1 - 0.65) / 100)

-1.645 %26gt; (phat - 0.65) / sqrt( 0.65 * (1 - 0.65) / 100)

Hello,

I'm doing some independent research. I would like to create my own survey in order to find out eating preferences for Americans in the area of Asian cuisine.

Sample Question:

What is your preference in Asian Cuisine?

a. Japanese

b. Thai

c. Vietnamese

d. Chinese

e. Other

I would also like to data about the people who take the survey also. In other words, key demographic information, such as income, disposable incomes, number in household, etc.

I don't want to purchase these reports online because some of the questions I'd like to ask are very specific for a product I am planning on selling.

How can I conduct this type of survey on a very modest budget?

What resources are at my disposal?

Thanks,

U can tell the company that ur reviewing the cosmetics since ur a reporter in a ad agency and they are looking for a great article and since u happned to have a nice sensitive skin u were chosen to carry out with this particular assignment. I wonder all those in need of a good review may easly take u up on ur offer and help u with the makeup themselves for once atleast u'd come to know what will suit u best lol make a fake id if u can and give ur own home number so that if the company does counter check they wud end up calling ur own home and see to it that u have somebody answering the call lol hope this helps.

SPSS Query Independent Sample T Test?

2010-05-24T02:55:00.000-07:00

I am trying to get help with a survey I conducted. I will give the basics and hope there is someone who can help. I did this research prior but when going back to my excel file with the data, I am not able to duplicate so I am unsure if I changed the data in a different way to input into SPSS.

I surveyed a class. One teacher (one variable) and multiple students (second variable)

I had seven sections with seven questions in each section.

Respondents could answer yes (yes=1) or no (no= 0) to each question

I was comparing the means for each section for the one faculty member and all combined student means.

So the teacher could answer (yes, yes, no, yes, yes, no, yes) equaling a mean of .714

Say there are four students and their combined mean was .567

This is done for each section.

Thus I was trying to do the independent sample t test to see if the teacher’s responses were significantly different from the student’s responses.

Any help would be greatly appreciated.

Thanks

Dave

How hard is the actual CFA level one test relative to the sample questions given on their website?

2010-05-24T02:54:00.001-07:00

http://www.cfainstitute.org/cfaprog/cour...

According to the CFA website: "

To allow candidates to survey the rigor and question formats of each exam, we have several sets of sample questions."

I would emphasize "rigor" if I could. Anyway, I, as an undergraduate senior with a strong background in both economics and accounting, was wondering how difficult the first part of the CFA exam was relative to the sample questions given above. Are those questions less or more difficult than the ones on the actual exam?

If they are less/more difficult than the actual examination questions, could you point me to a good source that has test questions that accurately reflect the tests difficulty?

How hard is the actual CFA level one test relative to the sample questions given on their website?
The difficulty of level I consists in two aspects:

1. the scope

2. Time

You have only a limited amount of time for each question, the exam covers a wide range of different topics. But you have the right background so you should emphasize the time constraint aspect when preparing for the exam, by doing practice questions under a time constraint.

Schweser or Stalla have good prep materials including booklets with entire past exams. Sometimes You can get past year's practice exams on ebay.

walmart.com - click on "in stores now" and then "free samples"

they have john frieda hair care, nivea, tampax, advil, always, kotex, etc and they change the samples every week or two.

also, you can go to various sites like dove, kashi, etc. and get samples from the brands directly.

i have a bunch of links for you in the sources!

also, i have been using wal-mart.com to get samples for a long time and they always come within a few weeks and are great!

*none of these require you to fill out more than your name and address! so no crazy offers, surveys or credit card info!

She can always do a poem:

If she's a funny girl, tell her to stand up to the bride and groom and say. "(insert brides name here) told me to I had to give a toat to the bride and groom, so here it is," she says while pulling out a piece of toast. Of course follow this with something sweet about the couple.

No matter what thw speech is, always:

State how beautiful the couple is.

Give best wishes to the bride and congradulate the groom.

Give a blessing of hoping for a happy future together.
Reply:Hey, why think of something personal on your own, when you can just download someone's else thoughts and good wishes for free?
Reply:All speeches should come from the heart not a website... what kind of friend copies a prepared speech. just keep it short and simple, with a little humor and a lot of love.

Difference between "Sample Size" and "Group Size"??

2010-05-24T02:52:00.001-07:00

In my online AP Statistics class, our final project is to conduct a survey and then analyze the data. Well, one of the questions as part of my analysis is "What is the size of the sample? the group sample? (Explain why) " What's the difference?! I had 50 subjects. And what exactly am I to explain? thanks so much for any help.

Difference between "Sample Size" and "Group Size"??
the group size is 50 because that is how many people that participated and the sample size is how many people responded yes and how ever many responded no.
Reply:as far as i know the basic difference between both is tht a sample is an individual and holds lminority whereas group signifies togetherness and holds majority
Reply:Within those fifty subjects, there are a few that fall outside the mean. These are the students at the far end of both sides of the scale. They don't really mean anything because they are too far away from the group and just dilute the results. The sample size is the group toward the center of the sample, where you have the most results that hit the mark. Lets say you have fifty students and forty six of them get between 86 and 100 on a test. One of them gets a zero because he just wrote his name on the paper and doodled for the rest of the period. One got a forty because he was sick that day and couldn't stay awake long enough to finish. The ones outside the means (between 86 - 100) are the ones that you don't include in the study becuase they just confuse your results. Hope this helps.

Stratify random sample?

2010-05-24T02:52:00.000-07:00

a principle wants to survey the student body about the convenience and security of the student parking lot. the statistics teacher recommended a stratified samole, but the got interrupted before he could explain what that meant. decide what factor the principal should use to stratify and explain how the principal could produce a stratified sample with 100 students.

Stratify random sample?
the principle could stratify by grade, by gender, or anything. Then, divide 100 by the number of categories (for example, there are 4 grades in high school), so you would get 25 people in each category to add up to 100.

Feel free to let me know which mental health illness/illnesses you have. Its part of my health and social care coursework :p (your information would be kept confidential, Im only going to use the statistics)

Remember, a mental health illness could be: anorexia, OCD, depression, paranoia as well as schizophrenia, phobia, autism, anxiety disorder.....

Thanks a lot.

W4003-Determine the sample size needed to estimate this population proportion to within + .02 with 95% ....?

2010-05-20T23:43:00.001-07:00

W04003

The results of a survey conducted by the Sierra Club in the spring of 1999 indicate that voters in the United States supported the idea of more public money being spent on conservation (Haya El Nasser, "Conservation has clout in Congress," USA Today, May 11, 1999, p. 13A). In a survey of 861 registered voters, half the people indicated that they would rather spend $2 billion of the federal government's budget surplus to protect wildlands than on national defense. Suppose that you wished to conduct a follow-up survey to estimate the proportion of U.S. voters who currently favor such a proposal. Determine the sample size needed to estimate this population proportion to within + .02 with 95% confidence.

W4003-Determine the sample size needed to estimate this population proportion to within + .02 with 95% ....?
n = z^2( sqrt(p(1-p)/0.02)^2)

Where z = 1.96 and p = 0.50 (half the population)

n = (1.96)^2(sqrt(0.25)/0.0004) = 96 voters

What kind of statistical tests should I use?

2010-05-20T23:43:00.000-07:00

Suppose 100 individuals were surveyed and each of them was asked for their preference of dishes A, B, C %26amp; D from a scale of 1 to 5. I want to compare if there is significant difference between the means of the dishes.

Is it a dependent or independent sample ?

What kind of test should I use?

Thank you in advance.

What kind of statistical tests should I use?
A Chi - squared test.

The table would have in the columns the responses options, 1 through 5. the rows would be for the dishes.

______ 1 _ 2 _ 3 _ 4 _ 5

dish A

dish B

dish C

dish D

the table would be field in with the number of responses for each responses.

The chi squared test uses the null hypothesis that the rows are all independent and identically distributed multinomial trials. The alternate hypothesis is that at least one of the rows does not follow the same distribution as the others.

Statistics survey help?

2010-05-20T23:42:00.003-07:00

I am doing a survey to see if there is a correlation between the hours worked and absences of students. There was no correlation between the two but there is a question of what would be the next step if you were going to do further reasearch. Other than a larger sample size, what could I put?

thanks:)

Statistics survey help?
Ha ha, I'm in statistics right now and just finished typing up my own statistics project. :)

A different sample type; such as blocking, stratifying, etc. depending on what you're trying to get in your survey. (Do you want to generalize the study for the whole population or for a specific part of it)

Varying the people you survey; including more types of people/socioeconomic classes/whatever.

A more random sample

How should I compensate for the medthod of selection?

2010-05-20T23:42:00.002-07:00

I am conducting a statistical survey about hours of sleep vs. grades among the students in a school from 6th-12th grade. I will be sampling 4 students from each grade level. As of now my plan is to stand in a communal area and randomly select students to survey, however I am concerned about self-selection and bias. I am looking for suggestions about ways to account for any bias, or an entirely different method of sampling. I am open to all suggestions. Thanks!

How should I compensate for the medthod of selection?
First of all you need to broaden your sample size. You're using 7 grade levels with four students from each which means N=28. Not much to base your conclusions on...As for selecting if you yourself are choosing the subjects then you're correct. You have just introduced bias into your study. Give everyone a number and then have a teacher or someone else draw the number from a hat. Perhaps you could even search online for a Random Number Generator.....Good luck and great topic to study by the way.

The nonprofit group Public Agenda conducted telephone interviews with three randomly selected groups of parents of high-school children. There were 202 black parents, 202 Hispanic parents, and 201 white parents. The sample survey asked the parents to respond to the statement, “A college education has become as important as a high school diploma used to be." Here are the counts of responses:

Write a brief report on the similarities or differences among the three groups of parents in their attitudes towards the importance of a college education. Include a graph or graphs and a test of significance.
