One week, Ginger decided to collect tutorial satisfaction ratings (0-10) from students enrolled in the first (Monday 8am, N = 17) and last (Friday 4pm, N = 18) scheduled 2203 classes. She calculated the pooled variance of the differences scores and found that the standard error was 1.3. The mean satisfaction ratings were 5.5 and 7.1 respectively.

Is there a statistical difference between the mean satisfaction ratings for each class?
