3.2 Voting and personal views. In May 2015, the Gallup Poll asked a random sample of 1024 American adults, “Thinking about how the abortion issue might affect your vote for major offices, would you only vote for a candidate who shares your views on abortion or consider a candidate’s position on abortion as just one of many important factors or not see abortion as a major issue?” It found that 21% of respondents said they will only vote for a candidate with the same views on abortion that they have. Suppose that the sample size had been 4000 rather than 1024. Find the margin of error for 95% confidence in this case. How does it compare with the margin of error for a sample of size 1024?
