You want to obtain a sample to estimate the proportion of a population that possess a particular geneticmarker. Based on previous evidence, you believe approximately p*= 23% of the population have thegenetic marker. You would like to be 98% confident that your estimate is within 4% of the true populationproportion. 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.
