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 5412 patients were given clopidogrel, and 6643 were given ticagrelor. Of the clopidogrel patients, 612 suffered a heart attack or stroke within one year, and, of the ticagrelor patients, 660 suffered a heart attack or stroke. Can you conclude that the proportion of patients suffering a heart attack or stroke is less for ticagrelor? Use the ?? = 0.09 level.
