3. 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 6676 patients were given clopidogrel, and 6732 were given ticagrelor. Of the clopidogrel patients, 668 suffered a heart attack or stroke within one year, and of the ticagrelor patients, 569 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 = 0.01 level. a. State the null and alternate hypotheses. (1 point) b. Sketch sampling distribution, indicating the critical (rejection) region(s) and show the critical value(s) and test statistic on the sketch. (3 points) c. State your conclusion for this hypothesis test. (1 point) d. Interpret your conclusion in the context of the original claim. (3 points} e. Construct and interpret the appropriate confidence interval (using the given significance level) for the difference in the proportion of patients who suffered a heart attack or stroke for the two drugs. (2 points)
