A. Parameter

When Dennis calculates the mean age of the people who shop at the mall, he will be calculating a parameter. A parameter is a numerical summary of a population, which is the entire group of individuals or items of interest. In this case, the population would be all the people who shop at the mall.

A statistic, on the other hand, is a numerical summary of a sample, which is a subset of the population. If Dennis were calculating the mean age of a sample of shoppers, it would be a statistic. But since he is calculating the mean age of all the shoppers at the mall, it is a parameter.
