Stan is conducting a class research project in which he compares manual dexterity in two groups of randomly assigned participants: one group is sober and the other has consumed 2 ounces of 75 proof alcohol. what statistical test should stan use to see whether the two groups differ in manual dexterity?

t-test

Explanation:

t-test is an inferential statistic analysis which is used to determine whether there is a difference between mean score of two groups. Here, we have two groups with one independent  variable (manual dexterity), so t-test is appropriate.

your answer should be c, it seems to be the only one that makes sense. mark me branliest : )
