A researcher believes that the fraction (p₁) of Republicans in favor of the death penalty is greater than the fraction (p2) of Democrats in favor of the death penalty. She acquired independent random sample of 200 Republicans and 200 Democrats and found 136 Republicans and 124 Democrats favoring the death penalty. Do these data support the researcher's belief? Test the appropriate hypotheses using a=0.05. a. State the appropriate hypotheses. b. Calculate the value of the test statistic. c. Determine the rejection region. d. What is your conclusion? Interpret your conclusion. D
