Section D: A research team believes that the systolic blood pressure of adult males is normally distributed with a population variance equal to 400. A simple random sample of 36 males selected from the adult male population had a mean systolic blood pressure reading of 130. Let u denote the mean systolic blood pressure of adult males. Suppose the research team wants to test, at the 5% level of significance, whether the mean systolic blood pressure of adult males is not equal to 135. Suppose the assumptions of this hypothesis test are satisfied.
