Estimates from Voter Surveys In a recent presidential election, 611 voters were surveyed and 308 of them said that they voted for the candidate who won (based on data from the ICR Survey Research Group).

a. Find the point estimate of the percentage of voters who said that they voted for the candidate who won.

b. Find a 98% confidence interval estimate of the percentage of voters who said that they voted for the candidate who won.

c. Of those who voted, 43% actually voted for the candidate who won. Is this result consistent with the survey results? How might a discrepancy be explained?
