Answer

Brief Explanations:

In statistics, the population is the entire group of interest, and the sample is a subset of the population. Here, the grocery - store chain wants to know the opinion of all its customers about the change to self - checkouts. So the entire set of customers is the population. Since it's impossible to ask every customer, they survey shoppers in 25 randomly selected stores. Shoppers surveyed in those 25 stores are a subset of the total customers, making them the sample.

Answer:

The population for this survey is all customers of the national grocery store chain. The sample is the shoppers surveyed in the 25 randomly selected stores.
