Question: Suppose that you want to find a 95 confidence interval

Suppose that you want to find a 95% confidence interval based on independent samples for the difference between two population proportions and that you want a margin of error of at most 0.01.
a. Without making an educated guess for the observed sample proportions, find the required common sample size.
b. Suppose that, from past experience, you are quite sure that the two sample proportions will be 0.75 or greater. What common sample size should you use?
