You want to obtain a sample to estimate a population proportion. Based on previous evidence, you believe the population proportion is approximately p ∗ = 23 % p ∗ = 23 % . You would like to be 99.5% confident that your esimate is within 0.5% of the true population proportion. How large of a sample size is required? n =
