The Center for Disease Control and Prevention (CDC) estimates that, on average, 5% to 20% of the U.S. population gets the flu cach year. Using 20% as our best guess (p*), find how large a sample would be needed to get a ±2 percentage point margin of error on a 95% confidence interval for the population proportion of Americans who get the flu in a given year. (Enter your answer as whole number.) Sample size:
