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

Before
38.6
41.2
37.9
38.6
42.6
After
37.0

43.6
Is there sufficient evidence to suggest that the relaxation
exercise slowed the brain waves? Assume the population is normally
distributed.
Select the test statistic, p-value, Decision to Reject
(RH0) or Failure to Reject (FRH0)].
a) [t = 2.214, p-value = 0.023,...
