Due 3/3/99

1.
A major midwestern university wishes to see if a change in the prerequisites for first semester physics has any effect on student's performance. We list below the results of the first midterm exam. The first group of scores is for students with the traditional prerequisites, and the second list is for the experimental prerequites. Can you detect any statistical differences?
