Politics and Sex One month before the election, a poll of 630 randomly selected voters showed 54% planning to vote for a certain candidate.  A week later, it became known that he had an extramarital affair, and a new poll showed only 51% of 1010 voters supporting him.  Do these results indicate a decrease in voter support for his candidacy? Test an appropriate hypothesis and state your conclusion If you concluded there was a difference, estimate that difference with a confidence interval and interpret your interval in context
