An aircraft has 200 seats, and there are two types of fares: full ($599) and discount ($199). a) While there is unlimited demand for discount fares, demand for full fares is estimated to be Poisson with mean lambda =20 (the table below gives the distribution function). How many seats should be protected for full-fare passengers? b) (Independent of part (a)) An airline has found that the number of people who purchased tickets and did not show up for a flight is normally distributed with mean of 10 and standard deviation of 5. The airline estimates that the ill will and penalty costs associated with not being able to board a passenger holding confirmed reservation are estimated to be $600. Assume that opportunity cost of flying an empty seat is $199 (price that discount passenger would pay). How much should airline overbook the flight?
