Airline Delays. Suppose you are a scheduler for a major airline, analyzing a distribution of flight delays (departures) during one day at an airport. The distribution of delay times has the following properties: The mean delay is 10 minutes, the median delay is 6 minutes, the mode of the distribution is 0 minutes, and the maximum delay is 25 minutes. a. Draw a rough sketch of the distribution with clearly labeled axes. Is the distribution skewed (and if so, which way) or symmetric? b. What percentage of flights were delayed less than 6 minutes? c. What percentage of flights were delayed more than 6 minutes? d. Discuss the pros and cons of using the mean and the median to present the average flight delay of your airline to the public.
