Suppose we want to conduct a poll to estimate the proportion of voters who approve of the current mayor, and we plan to use a 95% confidence interval for our estimate.
Determine the sample size needed so that the sample proportion is within a margin of error of .025 of the true proportion of all voters who approve of the mayor.
You will have to assume in your computation that 50% of the electorate could approve of the mayor.
