The accompanying table shows the result of a national election
along with the vote predicted by several organizations in the days
before the election. The sample sizes were typically a bit above​
1,000 people, and the reported margin of error was around plus or
minus 3 percentage points. The percentages for each poll may not
sum to 100 because of voters who indicated they were undecided.
1. The News Network 1 poll predicted that 50​% were going to
vote for Candidate A​, with a margin of error of plus or minus
3​%.
The true proportion of voters for Candidate A is within 3
percentage points of 50%.
Question: Do most of the predictions fall
within the margin of error of the actual vote​ percentages?
A. Yes, because all predictions are within the margin of error
of the actual vote percentages.
B. Yes, because all predictions are within the margin of error
of the actual vote percentages except for Polling Company 1.
C. No, because only predictions by News Network 2 are within the
margin of error of the actual vote percentages.
D. ​Yes, because all predictions are within the margin of error
of the actual vote percentages except for News Network 2.
