# One-sided hypothesis testing

Please, check the following problem from the exam:

Could you check the following logic:

1. H$_{0}$: difference in the ratings = 0
2. H$_{a}$: difference in the ratings > 0, because human resources manager wants to determine an increase in the ratings
3. Based on (2) I conclude that it is right-sided test and positive critical value of the test statistics is needed.

Am I right? Thanks.
