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

Does anyone know how to solve this statistics problem?
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.

I'm stuck on a homework question.?
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?
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

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....?
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

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

Stats Survey Analysis?
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.

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.

They usually have some goodies you can sign up for. You should also sign up for BzzAgent (http://www.bzzagent.com). You try out products, that they send to you for free, and you provide reviews, fill out quick surveys about the product. Each review earns you BzzPoints, which you can redeem for rewards. In the last year, I've gotten a SonicCare toothbrush for free to try out and review; got a pair of Sony sound-cancelling headphones as a reward by using my points. I am not lying when I say it is TOTALLY FREE.
Also, try sending a complimentary letter or email to the headquarters for some of your favorite products. I've gotten lots of coupons that way.
Reply:The word FREE in a misnomer! Nothing is free. Anytime you sign up for FREE stuff, you should know that that web site is placing 'cookies' in your computer that track your activity on the World Wide Web. You then will receive numerous SPAM in your e-mail. Bummer isn't it? The way to beat that is to set up a throwaway e-mail address that all of the SPAM goes to. Yahoo Mail is pretty good at separating Spam. So try that if you must browse the free-bees. Good Luck
Reply:www.beinggirl.com for feminine products and www.pantene.com for free shampoo products. I know beinggirl works because I signed up for it myself and got them, they are really worth it. I saw pantene on TV so I am sure it works. Hope this helps!

Do you get statistics?
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."

Directions:you want to find out if a school bond issue for a new computer center is likely to pass in the next election. State whether each survey plan describes a good sample. Explain your reasoning.
5. You interview people coming out of a computer store in your town.
6. You choose people to interview at random from the city telephone book.
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 DRA sample sheets to administer to a student for practice!?
I'm taking RED 4519 in college. I'm majoring in Elementary Education. This class requires me to do a mock assessment on a student. 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!
I need to print out DRA sample sheets to administer to a student for practice!?
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!

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.

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)

What is the best way to conduct an online survey?
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,
Pete

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?
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

Where can I find free samples without having to join or have a credit card?
I am looking for sites to get free samples of all kinds of products but do not want to join or have to put a credit card up or have to take surveys.
Where can I find free samples without having to join or have a credit card?
Your requested is limited in the market as the substitutes products may think you are the competitor for them, except you personnel visit the promotion place or factory .I normally get the free simple from happy hours/promotion days at hypermarket.Good luck!
Reply:You can't. Because it's not really free. At the very least they want your contact information so they can spam you to death.
Reply:Usually the best place to get free samples of stuff is in magazines where you can mail in, or call in, or order online. If you go to Home and Garden road shows and stuff lots of free stuff at those. Enter for drawings and stuff online.
Reply:google and maybe find out there
Reply:Costco, find a buddy that has a card and have them take you there. You wont have to join nor will you have to use a credit card.

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

Tease the people that have to hold their urine in till it's their turn to pee.

What are some totally free web sites for bride's maid speeches?
I agree that the best speeches come from the heart... but you werent asking anyones opinion, right? :) Don't worry about the evil commenters, we should all be here to help you.
Some examples:
http://www.frugalbride.com/maidofhonours...
http://www.freeweddingtoasts.net/free-we...
http://quotations.about.com/cs/weddingto...
She can always do a poem:
http://www.authorsden.com/visit/viewpoet...
http://www.poemsforfree.com/wedpo.html
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.

I have find the number of people from the sample who like amazinf soda. I already found the sample which is 3257. Does anyone know if you can find how many people actually like amazinf soda from this? Could you please show me how you got the answer too? Thanks :)
