1. The Central Limit Theorem for the proportion requires np >= 10 and n(1-p) >= 10, and that the sample was collected using an SRS. If these requirements are met, then the distribution of the sample proportion is approximately normal. If we know that the population proportion is p, what are the mean and standard deviation for the distribution of the sample proportion? Assume you know that n = 1002 and p = .50. Use this information in problems 2-4....
