The following data are from a repeated-measures study examining the effect of treatment by measuring a group of n=6 participants before and after they receive treatment.

Participant	Before Treatment	After Treatment
A	7	8
B	2	9
C	4	6
D	5	7
E	5	6
F	3	8

a(6 pts).State the Null and Alternative hypotheses.

b(14 pts).Is there a significant treatment effect? Use a two-tailed test with alpha 0.05. Compare p-value to alpha. What do you conclude (e.g., "reject" or "fail to reject" the Null hypothesis)?

c(5 pts).State the conclusion in the words of the problem.
