Determine the sample size required to estimate a population

Determine the sample size required to estimate a population proportion to within 0.032 with 99.2% confidence, assuming that you have no knowledge of the approximate value of the sample proportion. (You will need to use software to get your critical value and should expect to use 4 decimal places of accuracy.) Sample Size = B. Repeat part the previous problem, but now with the knowledge that the population proportion is approximately 0.25.
