The following table shows the percentage of on-time arrivals, the number of mishandled baggage reports per 1000 passengers, and the number of customer complaints per 1000 passengers for ten airlines (Forbes website, February 12, 2014). If you randomly choose a Delta Air Lines flight, what is the probability that this individual flight has an on-time arrival? If you randomly choose one of the ten airlines for a follow-up study on airline quality ratings, what is the probability that you will choose an airline with less than two mishandled baggage reports per 1000 passengers? If you randomly choose one of the ten airlines for a follow-up study on airline quality ratings, what is the probability that you will choose an airline with more than one customer complaint per 1000 passengers?
