An airline wants to survey its customers to ask them: "Do you approve of limiting the number of carry-on bags to a maximum of one bag?" Airline managers expect that only about 25% will say "yes." Based on this assumption, what size sample should the airline take if it wants to develop a 95% confidence interval estimate for the population proportion who will say "yes" with a margin of error of 4%? 601 451 10 93 115
