Answer 4

1. To determine the population for this situation, we need to consider who we are trying to gather information about. In this case, the manager of the Millcreek Mall wants to know the mean age of the people who shop at the mall, so the population would be answer A: all of the people who shop at Millcreek Mall. This includes all ages and genders of the mall shoppers.

2. The sample, on the other hand, refers to the specific group of people that Dennis interviews. In this case, he interviews 100 people on a busy Saturday at the mall, so the sample would be answer B: the 100 shoppers that Dennis interviews. This sample is a subset of the larger population of mall shoppers.

3. When Dennis calculates the mean age of the people who shop at the mall, he will be calculating a statistic. A statistic is a numerical summary of a sample, while a parameter is a numerical summary of a population. Since Dennis is only collecting data from a sample of 100 shoppers, the mean age he calculates will represent a statistic rather than a parameter.
