**CFA Practice Question**

True or False? If False, correct the statement.

If the population mean is known, it makes no sense to test hypotheses concerning the population mean.

Correct Answer: True

The purpose of a hypothesis test is to draw a conclusion about a population based on a sample. If the population is known, there is nothing to hypothesize.
