h₀ : alcohol has no effect on college students emotions

4. the alternate hypothesis:

h₁: there is effect of alcohol on college students emotions

5. The researcher would have to use a t test which is an inferential statistical test. A t test is used to test for the existence of statistical difference between two means that may have similar features
