2. Because many passengers who make reservations do not show up, airlines often overbook flights (sell more tickets than there are seats). A Boeing 767-400ER holds 245 passengers. The airline believes the rate of passenger not showing up is 5% and sells 255 tickets. [10 Marks] a. Use Normal approximation to determine the binomial probability of at least 246 passengers showing up. [9 Marks] b. Should the airline change the number of tickets it sells for...
