Step-by-step explanation:

The population is every individual relevant to an investigation from whom the sample is taken;

In this case, the mean age of people who shop at the mall is being investigated and therefore all of the people who shop at the mall are the population.

A sample is a group of representative individuals chosen from the population to be studied to investigate some aspect of the population;

A sample is usually taken because studying or testing every individual would be problematic and not generally neccesary;

In this case, the sample would be the hundred shoppers chosen to be interviewed.

A parameter and (test) statistic are almost the same thing, but a parameter is the value (or range of values) of some characteristic of the whole population, whilst a statistic is the value (or range of values) of some characteristic of just a sample of the population.
