A bookstore in the mall is trying to determine how many mall shoppers are interested in purchasing books as gifts. To obtain a random sample, the manager surveys every third person that enters the
bookstore.
Does the sample represent the population? Why or why not?
Select the option that correctly answers both questions.
O yes, because people who are already searching for books will give the best responses
O yes, because every third person that enters the bookstore is representative of all
shoppers in the mall
O no, because the manager needs to survey every person that enters the bookstore in
order to represent the population
O no, because people in the bookstore are interested in purchasing books, so they do
not represent all shoppers in the mall
