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 38 66 49 29
after 26 36 59 52 24
assuming the population is normally distributed, 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.
