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 37.2 41.7 37.4 37.2 38.8 After 31.6 37.3 33.1 33.3 37.7 Is there sufficient evidence to suggest that the relaxation exercise slowed the brain waves? Assume the population is normally distributed. Select the [p-value, Decision to Reject (RH0) or Failure to Reject (FRH0)].
