CR13.3 The article “Fines Show Airline Problems” (USA Today, February 2, 2010) gave the accompanying data on the number of fines for violating FAA maintenance regulations assessed against each of the 25 U.S. airlines from 2004 to 2009.

1 12 3 7 23 36 6 14 1 3 4 10 6 2 2 2 2 2 3 1 2 2 1 0 0

a. Construct a boxplot of these data. Are any of the observations in the data set outliers? If so, which ones?

b. Explain why it may not be reasonable to assume that the two airlines with the highest number of fines assessed are the worst airlines in terms of maintenance violations.
