11. Political Corruption A questionnaire is designed to investigate attitudes about political corruption in government. The experimenter would like to survey two different groups—Republicans and Democrats—and compare the responses to various “yes/no” questions for the two groups. The experimenter requires that the sampling error for the difference in the proportion of

“yes” responses for the two groups is no more than 63 percentage points. If the two samples are the same size, how large should the samples be?
