A. Determine the sample size required to estimate a population proportion to within 0.032 with 97.8% 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 0.28.

Sample Size =?
