The difference in the average age of the sample and the population is probably due to sampling error

<h3>What is sampling error?</h3>

The sampling error in a statistical data is simply an error that arises when a sample that represents the population is not properly selected or analyzed

From the question, we have the following parameters:

$\bar x = 21.2$ -- the sample average

$\mu = 19.4$ -- the population average

Notice that:

$\bar x \ne \mu$

i.e. sample and the population averages are not equal.

This difference is often as a result of sampling error
