Preventing heart attacks: Medical researchers performed a comparison of two drugs, clopidogrel and ticagrelor, which are designed to reduce the risk of heart attack or stroke in coronary patients. A total of 6650 patients were given clopidogrel, and 6710 were given ticagrelor. Of the clopidogrel patients, 650 suffered a heart attack or stroke within one year, and of the ticagrelor patients, 580 suffered a heart attack or stroke. Can you conclude that the proportion of patients suffering a heart attack or stroke is less for ticagrelor? Let p, denote the proportion of patients suffering a heart attack or stroke with clopidogrel and p, denote the proportion of patients suffering a heart attack or stroke with ticagrelor. Use the a=0.01 level of significance and the critical value method. Part 1 of 5 State the null and alternate hypotheses. Ho: P1= P2 H: P1> P2 This hypothesis test is a right-tailed test. Part 2 of 5 Find the critical value(s). Round the answer(s) to two decimal places. If there is more than one critical value, separate them with commas. Critical value(s): 2.326 Microsoft Power Part: 2 /5
