Because many passengers who make reservations do not show up, airlines often overbook flights (sell more tickets than there are seats). A certain airplane holds 230 passengers. If the airline believes the rate of passenger no-shows is 9 sells 249 tickets, is it likely they will not have enough seats and someone will get bumped? a) Use the normal model to approximate the binomial to determine the probability of at least 231 passengers showing up. b) Should the airline change the number of tickets they sell for this flight? Explain. a) The probability of at least 231 passengers showing up is (Round to three decimal places as needed.) b) Should the airline change the number of tickets they sell for this flight? Explain. O A. The probability is fairly low, so it is likely that they should not change the number of tickets they sell. However, the decision also depends on the relative costs of not selling seats and bumping passengers. O B. Since the probability is so high, they should not change the number of tickets they sell. O C. Since the probability is so low, they should change the number of tickets they sell. O D. The probability is fairly high, so it is likely that they should sell less. However, the decision also depends on the relative costs of not selling seats and bumping passengers. ) Time Remaining: 00:28:19
