High blood pressure is a leading cause of strokes. Medical researchers are constantly seeking ways to treat patients suffering from this condition. A specialist in hypertension claims that regular aerobic exercise can reduce high blood pressure just as successfully as drugs, with none of the adverse side effects. To test the claim, 50 patients who suffer from high blood pressure were chosen to participate in an experiment. For 60 days, half the sample exercised three times per week for one hour; the other half took the standard medication. The percentage reduction in blood pressure was recorded for each individual; the resulting data are shown in the table below Exercise Medication Can we conclude at the 1% significance level that exercise is at least as effective as medication in reducing hypertension?
