Question

A well-known supermarket in the U.S. wants to determine what percent of storegoers are vegetarian. They randomly survey 5 people every hour at one of their grocery stores for a day.

This sample size is appropriate for the results to be generalized for all of the supermarket’s U.S. stores.

True
False

Answer 1

False

The sample size of 5 people surveyed per hour is too small to be generalized to all of the supermarket's U.S. stores. To accurately determine the percentage of vegetarian storegoers, a larger sample size and more stores should be included in the study.
