Let {L1 , L2 , . . . , L10 } indicates the amount of minutes late for 10 consecutive flights, i.e. X = L1 + L2 + · · · + L10 . It is given that ”weather” and ”flight jam” are the two principal factors for flight delay. That implies that L1 , L2 , . . . , L10 are correlated. Assumption.1: E(X ) = E(L1 + L2 + · · · + L10 ) = 10(15) = 150. This is a reasonable assumption. ￿ √ Assumption.2:...
