Use the information to answer the following question. A news show displays the results of a poll for a two-candidate runoff election between candidate A and candidate B. The poll shows that candidate A is leading with 53% of the vote. In small print, below the poll results, it says +4.9%. Which of the following statements about this poll is TRUE? The poll should not be trusted since it has a margin of error attached to it. O We can predict with 100% confidence that Candidate A cannot get more than 58% of the vote. Candidate A cannot be predicted as the winner because it is possible that a percentage of voters for him is less than 50%. Candidate A will win because the mean percentage for the poll is greater than 50%.
