63. Public relations. According to the U.S. Department of Transportation (DOT), passengers filed more complaints about airline service in 2007 than in 2006.

One airline’s public relations department says that their airline rarely loses luggage. Furthermore, it claims that when it does, 90% of the time the bags are recovered and delivered within 24 hours. A consumer group surveys a large number of air travelers and finds that 103 of 122 people who lost luggage were reunited with their missing items within 24 hours. Does this cast doubt on the airline’s claim? Explain.
