Note: Professor wants me to conduct this scenario using an independent sample T Test. To my knowledge, a bar graph is acceptable, but I am having trouble with conducting a test using the numbers depicted below.

Scenario: A psychology instructor at a large university teaches statistics. There are 22 students in the class, and he has broken them into two groups. Each group has a different graduate assistant who is responsible for running separate breakout lecture and lab sections of the course. One graduate assistant (GA) has lots of experience teaching, while the other has more limited experience. The instructor wants to check for comparable learning across the two GAs, hoping students receive similar experiences (i.e., to find no difference). The data below are the scores (out of 100) of the students on the first midterm. Use it to test whether there is a difference between the groups.

Group 1 (less experienced GA)	Group 2 (more experienced GA)
60	70
65	85
69	72
58	83
57	81
59	69
52	65
72	75
70	79
65	71
75	80
