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 5663 patients were given clopidogrel, and 6527 were given ticagrelor. Of the clopidogrel patients, 515 suffered a heart attack or stroke within one year, and, of the ticagrelor patients, 503 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 a = 0.05 level. a. State the null and alternative hypotheses. Ho : ? ?
