Question

In a experiment on relaxation techniques, subject's brain signals were measured before and after the relaxation exercises with the following results:

Person	1	2	3	4	5
Before	31	38	64	51	31
After	26	36	58	49	24

Is there sufficient evidence to suggest that the relaxation exercise slowed the brain waves? (Use α=0.05)

a) Reject the null hypothesis which states there is no change in brain waves in favor of the alternate which states the brain waves slowed after relaxation.

b) Fail to reject the null hypothesis which states there is no change in brain waves.

c) There is not enough information to make a conclusion.
