You want to obtain a sample to estimate a population proportion. At this point in time, you have no reasonable estimate for the population proportion. You would like to be 99% confident that you esimate is within 0.2% of the true population proportion. How large of a sample size is required? Do not round mid-calculation. However, use a critical value accurate to three decimal places.
