question 21 of 25
if a population is __, a sample of the population could be __.
a. all customers at a shopping mall; people who purchased shoes
b. passengers with window seats; all passengers on an airplane
c. registered state voters randomly selected for a poll; all citizens of the state
d. all professional football players; all professional athletes

Explanation:

A population is the entire group of interest, and a sample is a subset of that population. Option A correctly identifies "all customers at a shopping mall" as the population (entire group) and "people who purchased shoes" as a subset (sample) of that population. Other options reverse population and sample or use unrelated groups.

Answer:

A. all customers at a shopping mall; people who purchased shoes
