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 32 37 60 51 31 After 26 35 58 49 27 Is there sufficient evidence to suggest that the relaxation exercise slowed the brain waves? (Use α=0.05) a) There is not enough information to make a conclusion. b) 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. c) Fail to reject the null hypothesis which states there is no change in brain waves.

Question
In a experiment on relaxation techniques, subject's brain signals were measured before and after the relaxation exercises with the following results:
Is there sufficient evidence to suggest that the relaxation exercise slowed the brain waves? (Use α=0.05)
| Person | 1 | 2 | 3 | 4 | 5 |
| Before | 32 | 37 | 60 | 51 | 31 |
| After | 26 | 35 | 58 | 49 | 27 |
Is there sufficient evidence to suggest that the relaxation exercise slowed the brain waves? (Use α=0.05)
a) There is not enough information to make a conclusion.
b) 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.
c) Fail to reject the null hypothesis which states there is no change in brain waves.
