Airlines sometimes overbook flights. Suppose that for a plane with 50 seats, 55 passengers have tickets. Define the randor variable Y as the number of ticketed passengers who actually show up for the flight. The probability mass function of Y appears in the accompanying table. 45 46 47 48 49 50 51 52 53 54 55 P(Y) 0.05 0.10 0.12 0.14 0.25 0.17 0.03 0.06 0.05 0.02 0.01 Calculate V(Y) and oy. (Round your variance to four decimal places and your standard deviation to two decimal places.) V(Y) Oy = Determine the probability that Y is within 1 standard deviation of its mean value.
