Captopril is a drug designed to lower systolic blood pressure. The systolic blood pressure reading (mmHg) of subjects
were measured before and after they took the drug. Results are given in the accompanying table (based on data
from "Essential Hypertension: Effect of an Oral Inhibitor of Angiotensin-Converting Enzyme," by MacGregor et al.,
British Medical Journal, Vol. 2). Assume that the paired sample data is a simple random sample and that the
differences have a distribution that is approximately normal. Complete parts (a) and (b).

a. Use a 0.05 significance level to test the claim that captopril is effective in lowering systolic blood pressure.
Defined as the mean value of the differences d for the population of all pairs of data, where each individual difference
d is defined as the systolic blood pressure reading before captopril was taken minus the reading after captopril was
taken. What are the null and alternative hypotheses for the hypothesis test?
