Question
A group conducted a poll of 2071 likely voters just prior to an election. The results of the survey indicated that candidate
A would receive 46% of the popular vote and candidate B would receive 45% of the popular vote. The margin of error
was reported to be 2%. 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 mean to say the race was too close to call?
O A. 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.
OB.
Since the difference between the percentages of the popular vote for the candidates is less than the 9% of
voters that are undecided, the poll cannot predict the winner.
OC. 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.
O D. The margin of error suggests candidate A may receive between 44% and 48% of the popular vote and
candidate B may receive between 43% and 47% of the popular vote. Because the poll estimates overlap when
accounting for margin of error, the poll cannot predict the winner.
