QUESTION 2 Star Airlines also serves the route between Washington, DC (National), and Portsmouth, NH, with a single flight daily. The airline sells both discount-fare and full- fare tickets. The airline has assigned a 100-seat aircraft to the flight. Using Littlewood's rule, the airline has determined that the optimal booking limit for a flight departing in two weeks is 40. Question 1: The protection level for the flight is - (Hint: please round your answer to the nearest positive integer number. E.g., answers between 12345.01 and 12345.44 should be rounded down to 12345, and answers between 12345.45 and 12345.99 should be rounded up to 12346.). Question 2: The full fare for this flight is $200 and the discount fare is $100. Assuming that the full-fare demand follows a normal distribution, the mean full-fare demand for this flight is (Hint: please round your answer to the nearest positive integer number.). Hint: this question is a little bit tricky, but the given information is sufficient to determine the mean full-fare demand. Question 3: The flight controller has learned that the annual Yorkshire Terrier Fancier's Convention will be held in Portsmouth in two weeks. As a result, he increased the forecast of mean discount-fare demand by 50% over its previous value. The full-fare forecast remained the same. The new booking limits for this flight is (Hint: please round your answer to the nearest positive integer number.). Question 4: Right after learning about the Yorkshire Terrier Fancier's Convention, the flight controller learned that, due to maintenance problems, there will also be a switch capacity. Instead of a 100-seat aircraft, the flight will be served by a 120-seat aircraft. The new booking limits for this flight is (Hint: please round your answer to the nearest positive integer number.)
