eart attack or stroke within one year, and of the ticagrelor patients, 565 suffered a heart attack or stroke. Can you conclude that the proportion of patients uffering a heart attack or stroke differs between ticagrelor and clopidogrel? Let p₁ denote the proportion of patients suffering a heart attack or stroke with opidogrel and på 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 ethod. Part 1 of 5 State the null and alternate hypotheses. Ho: P₁ = P₂ H₁: P₁ P₂ This hypothesis test is a two-tailed test. Part: 1 / 5 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): X 5

Question
Transcribed Image Text: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 6700 patients were given clopidogrel, and 6714 were given ticagrelor. Of the clopidogrel patients, 669 suffered a
heart attack or stroke within one year, and of the ticagrelor patients, 565 suffered a heart attack or stroke. Can you conclude that the proportion of patients
suffering a heart attack or stroke differs between ticagrelor and clopidogrel? Let p₁ denote the proportion of patients suffering a heart attack or stroke with
clopidogrel and p₂ 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.
