Sample portion?

a marketing department surveys 1,500 shoppers and finds that 950 would visit a new store more often if it were open sunday evenings. What is the sample portion in this survey.

Sample portion?
Do you mean sample proportion?





That's the proportion of the people surveyed who said "yes."
Reply:950/1500=.63
Reply:The sample is the number of people asked the question in the first place. They are used as a representative "sample" of the population at large.





So, the sample is the 1,500 shoppers.
