Question 4You want to obtain a sample to estimate a population proportion. Based on previous evidence, you believe thepopulation proportion is approximately p = 0.76. You would like to be 96% confident that your esimate iswithin 4% of the true population proportion. How large of a sample size is required?

The population proportion is 0.76, confidence level is 96%, and margin of error is 0.04.
