Two competing airlines, Alpha and Beta, fly a route between Des Moines, lowa, and Wichita, Kansas. Each airline claims to have alower percentage of flights that arrive late. Let p, be the proportion of Alpha's flights that arrive late and p2 the proportion of Beta'sflights that arrive late.You are asked to observe a random sample of arrivals for each airline to estimate p, – P2 with a 90 % confidence level and a marginof error of estimate of 0.04. How many arrivals for each airline would you have to observe? (Assume that you will observe the samenumber of arrivals, n, for each airline. To be sure of taking a large enough sample, use p, = P2 = 0.5 in your calculations for n.)Round your answer to the nearest integer.

From the provided information, Margin of error (E) = 0.04 Confidence level = 90% Proportion (p1) =…
