Of the 1276 males that responded to this survey, 1111 agreed with this statement. Test to see if there is any difference between males and females with respect to how they feel about this issue. Use a significance level of .05.
State the appropriate null and alternative hypotheses.
Calculate the test statistic and report the p-value.
State your conclusion in context of the problem.
Based only on the results of the hypothesis test, would you expect a 95% confidence interval to include 0? Explain.
Calculate and interpret a 95% confidence interval for the difference between males and females.
