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 your estimate is within 5% of the true population proportion. How large of a sample size is required? n = Do not round mid-calculation. However, use of a critical value rounded to three decimal places will suffice.
