Question

Suppose that a random sample of 7 students who performed well on the homework was taken and weekly study times before and after the homework were compared. The resulting data are given in the table shown below. Assume that the population is normally distributed. It is known that s_before = 3.237 and s_after = 2.507.

Weekly Study in Hours of Students Who Perform Well on the Homework
Students	1	2	3	4	5	6	7
Before	17	8	12	11	17	13	14
After	10	8	9	10	15	13	9
