Expert Solution

Step 1
The derived numerical characteristic that explains the average (or mean) at the population level can be defined as the population mean. Whereas, the mean that is defined using a finite group of elements from the population (or sample) is defined as the sample mean. The higher the sample size is, the more precisely the sample mean estimates the mean at the population level.
