Q 8.19) A candidate is considering nominating for an election to become Mayor of a country town. Prior to officially nominating, the candidate decides to conduct a survey to assess the chances of being elected. Ninety voters are randomly selected with 55 indicating they will vote for the candidate. Find a 95% confidence interval for the proportion of voters in the town that will vote for this candidate. Based on this confidence interval, can the candidate determine whether or not to nominate for the election to become Mayor?
Homework Answers
Here n=90 is constant, 
z value for 95% CI is 1.96 as P(-1.96<z<1.96)=0.95
So Margin of Error is 
Hence CI is 
As CI both values are greater than 0.5 so Mayor can nominate for the election

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 49% of the popular vote and candidate B would receive 48% 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.

1 In the November 2016 election, Donald Trump received 49% of the votes cast in Florida (Hillary Clinton received 47%). Many news organizations conduct surveys before elections to try to predict the winner. Suppose a survey was conducted in Florida shortly before the election such that we can assume that the true proportion of the population who planned to vote for Trump was 49%. The pollsters surveyed 600 likely voters and found that 283 of them planned to vote for...
