A survey asked a random sample of adults in a nation two questions: (1) Would you favor or oppose a law which would require a person to obtain a police permit before he or she could buy a gun? (2) Do you favor or oppose the death penalty for persons convicted of murder? Results of the survey are available below. Does the sample evidence suggest the proportion of adults in this nation who favor permits for guns is different from the proportion of adult Americans who favor the death penalty for murder convictions? Use the a = 0.05 level of significance Click here to view the survey results. Click here to view the table of critical values of the chi-square distribution. Let p, represent the proportion who favor permits for guns and P2 represent the proportion who favor the death penalty. What are the null and alternative hypotheses? O A. Họ: P1 P2 H: P1 = P2 O B.
