Verified step by step guidance

1. Understand the definitions: A 'population' includes all members of a specified group, while a 'sample' is a subset of the population used to represent the group.
2. Identify the context: The problem describes a report showing the amount spent by each customer in a grocery store.
3. Determine the scope: If the report includes data for every customer who visited the store during a specific period, it represents a population.
4. Consider the alternative: If the report only includes data for a selection of customers, it represents a sample.
5. Conclude based on the information: Since the problem states 'each customer,' it implies that the data set includes all customers, indicating it is a population.
