To attract business, a clothing store mails discount coupons to local residents. To estimate the proportion of the store’s shoppers who are using the coupons, the store manager selects a random sample of 100 customers who visit the store on a weekend. The manager finds that 38 of them are using the coupons mailed to their homes. Which of the following describes the population in this setting?
Answer
A
all residents of the town
B
the 38 shoppers who used coupons
C
the 100 randomly selected shoppers
D
all shoppers in the store on the weekend
Explanation
The population is the entire group the manager wants to learn about. Since the manager is estimating coupon use among shoppers who visit the store on a weekend, the population is all shoppers in the store on the weekend. The 100 selected shoppers are the sample, and the 38 coupon users are part of that sample.
