A group conducted a poll of 2089 2089 likely voters just prior to an election. The results of the survey indicated that candidate A would receive 47 47% of the popular vote and candidate B would receive 45 45% of the popular vote. The margin of error was reported to be 3 3%. The group reported that the race was too close to call. Use the concept of a confidence interval to explain what this means. What does it mean to say the race was too close to call? A. Since the difference between the percentages of the popular vote for the candidates is less than the 8 8% of voters that are undecided, the poll cannot predict the winner. B. Since the estimated proportions depend on the level of confidence, the candidate predicted to receive the greater percentage of the popular vote changes for different levels of confidence, so the poll cannot predict the winner. C. Since the poll results do not show that one of the candidates has more than 50% of the popular vote, the poll cannot predict the winner. D. The margin of error suggests candidate A may receive between 44 44% and 50 50% of the popular vote and candidate B may receive between 42 42% and 48 48% of the popular vote. Because the poll estimates overlap when accounting for margin of error, the poll cannot predict the winner. Click to select your answer and then click Check Answer. All parts sh
