a. A prominent issue of the 2000 U.S. µresidential campaign was campaign finance reform. A Washington post/ABC News poll (reported April 41 2000) found that 63 percent of 11083 American adults surveyed believed that stricter campaign finance laws would be effective (a lot or somewhat) in reducing the influence of money in politics. Was this view uniformly held or did it vary by gender, race, or political party affiliation? A summary of survey responses, broken down by gender, is given in the table below.
Is there sufficient evidence in this survey to conclude that the proportion of individuals who believed that campaign finance laws can reduce the influence of money in politics differs between females and males? Set uµ the appropriate null and alternative hypotheses. Conduct your test at the .05 and .01 levels of significance and calculate the p-value for your test. Make sure your conclusion is clearly stated.
b. Search the World Wide Web for an interesting recent political poll dealing with an issue or political candidates, where responses are broken down by gender or some other two-category classification. (A list of high-potential websites is given below.) Use a difference in proportions test to determine whether political µreference differs by gender or other two-level grouping. |
