We want to perform a survey to answer the question: What proportion of California voters believe that Governor Newsom did a good job of steering California through the crisis caused by Covid-19? We plan to survey a random sample of California voters. We want to be able to make a 95% Confidence Interval which has a “margin of error" [what we've been calling E for the maximum likely error estimate and your book calls the 'EBP' for error bound for a proportion] of 3% = .03 Since we don't have any data from prior surveys, we'll play it safe and assume that p = .50 for our %3D calculation. Show your work to determine how many people should be surveyed.
