The sample mean is an estimate of the population mean.

The sample mean is exactly equal to the population mean

<h3>How to determine the true statement</h3>

When the population mean is known; the value of the population mean can be used as the sample mean.

This is so because:

The sample mean is an estimate of the population mean.

And it is represented as:

$\bar x = \mu$

Hence, the true statement is that the sample mean is exactly equal to the population mean
