You want to obtain a sample to estimate a population proportion. At this point in time, you have nc reasonable estimate for the population proportion. You would like to be 99.5% confident that you esimate is within 1% of the true population proportion. How large of a sample size is required? n = Do not round mid-calculation. However, use a critical value accurate to three decimal places. Question Help: DPost to forum Submit Question
