3/4 times 16/9 is equal to 1 1/3.
Considering the situation described, we have that:
- The appropriate null hypotheses is
.
- The appropriate alternative hypotheses is
.
<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:
.
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](https://tex.z-dn.net/?f=H_1%3A%20%5Cmu%20%3C%205.2)
