6.31. The exponential distribution can be used
to solve Poisson-type problems in which the intervals are not time.
The Air Travel Consumer Report published by the U.S. Department of
Transportation reported that in a recent year, Virgin America led
the nation in fewest occurrences of mishandled baggage, with a mean
rate of 0.95 per 1,000 passengers. Assume that mishandled baggage

of passengers between occurrences....
