A primary purpose of the poll was to obtain an estimate of the Proportion of potential voters who favored each candidate. Assume a planning value p* = .50 and a 95% confidence level. Question 8. %3D a. For p*= .50, what was the planned margin of error for the June poll? D. Closer to the November election. better precision and smaller margins of error are desired. Assume the following margins of error are requested for surveys to be conducted during the presidential campaign. Compute the recommended sample size for each survey.
