Hypothesis 1:
The teacher is concerned that there is a significant difference between the average midterm exam scores for the classes based on the number of days per week that the students attend class. Class 1 and 3 meet on Monday, Wednesday, and Friday, while Class 2 meets on Tuesday and Thursday. If there is a difference in the average midterm exam score for the classes, then she wants to know whether meeting three times a week is more or less effective than meeting only twice, and she wants to know how different these average midterm scores are.

1. Is there a significant difference in the average midterm grade, at the 5% level, between the classes that meet on M/W/F and those that meet on T/R? Yes or No.

2. If there is a significant difference, then tell which group has higher midterm scores on average and tell how much better the group does (with 95% confidence).
