Midterm scores for Math 160 in Winter, 2008 averaged 72.4 with a standard deviation of 12.8 (14 students).  Midterm scores for Math 160 in Summer, 2008 averaged 83.7 with a standard deviation of 7.9 (also 14 students). Is there enough evidence to conclude that, if these are representative samples of all Math 160 classes, summer classes perform better than winter classes in Math 160?
