11) (7 pts) An airline's public relations department says that the airline rarely loses passengers' luggage. It further claims that on those occasions when luggage is lost, 88% is recovered and delivered to its owner within 24 hours. A consumer group who surveyed a large number of air travelers found that only 132 out of 160 people who lost luggage on that airline were reunited with the missing items by the next day. At the 5% level of significance, do...
