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 5646 patients were given clopidogrel, and 6731 were given ticagrelor. Of the clopidogrel patients, 621 suffered a heart attack or stroke within one year, and, of the ticagrelor patients, 656 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 = 0.09 level. a. State the null and alternative hypotheses. Ho:? V ? Select an answer H: ? V ? Select an answer b. Find the critical value and sketch the rejection region. Sketch of Rejection Region: -3 -2 -1 0 1 2 3 -3 -2 -1 0 1 2 b 3 -3-2-10 1 a 2 3 Critical value(s): (If there are two critical values, list both values separated by a comma) c. Find the test statistic. d. Find the p-value.
