Question

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?

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

B.
This sample is too small.

C.
The sample is too large.

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

Answer 1

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

Explanation: By going door-to-door to nearby residents she excluded nonlocal customers (and other groups) who might visit the restaurant, so the sample is not representative of the restaurant’s future customer base.
