State your conclusions in terms of the context of the problem.

Does the time of day that a class meets affect exam grades? Exam grades for an 8am statistics class and a 3pm statistics class taught by the same professor were compared. The summary data are given in the table below. Assuming both populations are approximately normally distributed, is there a difference between the two classes? Use a significance level of 5%.

8am Class	3pm Class
= 23	= 27
= 81	= 85
= 8.6	= 11.2

Clearly label the 6 step approach
