Question list Question 1 Question 2 Question 3 Question 4 K 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). Before After OA.
