You want to obtain a sample to estimate the proportion of a population that possess a particular genetic marker. Based on previous evidence, you believe approximately p*= 25% of the population have the genetic marker. You would like to be 90% confident that your estimate is within 1.5% of the true population proportion. How large of a sample size is required? n = Do not round mid-calculation. However, you may use a critical value accurate to three decimal places.
