а) Twо cаndidаtes are running fоr US senatоr in Florida. One is Republican and the other is a Democrat. We don't have an idea of which is the preferred candidate.

(7 points) b) After you sampled your respondents, you found that 51% say they'll vote for the Republican and 47% say they'll vote for Democrat.

Say yes or no, and explain why they are within the margin of error or why they are not. (3 points)
