Verified step by step guidance

Understand the definitions: A 'population' refers to the entire group that you want to draw conclusions about, while a 'sample' is a subset of the population used to represent the population.

Identify the context: The problem mentions 'the amount spent by each customer in a grocery store.' This implies that the data includes all customers who visited the store.

Determine if the data set includes all members of the group: If the data set includes every customer who visited the grocery store, then it represents the entire population.

Consider the scope of the data: If the data set is limited to a specific time frame or a specific group of customers, it might be a sample. However, if it includes all customers without restriction, it is a population.

Conclude based on the information: Since the problem states 'the amount spent by each customer,' it suggests that the data set includes all customers, indicating that it is a population.
