Millie, a new restaurant owner, is trying to predict the restaurant’s busiest days and times so she can hire and schedule her workers. She went door-to-door to survey 50 residents in the same town as the restaurant. Which statement best explains why this is not a representative sample of her future customers?

Question

A.
The sample included only people who live close to the restaurant.

B.
The sample is too large.

C.
This sample is too small.

D.
The sample of people surveyed may not eat out at restaurants.

Answer 1

The statement that best explains why Millie's sample is not a representative sample of her future customers is:

A. The sample included only people who live close to the restaurant.

This option highlights the potential bias in the sampling method, as the opinions of residents who live near the restaurant may not reflect the preferences and behaviors of all potential customers, especially those who live farther away or who may come from different demographics or areas.
