Considering the situation described, we have that:

The appropriate null hypotheses is $H_0: \mu = 5.2$ .

The appropriate alternative hypotheses is $H_1: \mu < 5.2$ .

<h3>What are the hypotheses tested?</h3>

At the null hypotheses, it is tested if the mean has not been reduced, that is, it still is of 5.2 hours, hence:

$H_0: \mu = 5.2$ .

At the alternative hypothesis, it is tested if the mean has been reduced, that is, it is now of less than 5.2 hours, hence:

$H_1: \mu < 5.2$
