Question

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 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?

Answer 1

54% of 630 = 0.54 * 630 or approximately 340 of the 630 were planning to vote for the candidate.

51% of 1010 = 0.51 * 1010 or approximately 515 of the 1010 were planning to vote for the candidate.

This means that the voter support for this candidate increased.
