Question

Problem 1: In the film “Up in the Air”, George Clooney portrays a man whose job it is to tell workers that they have been fired. The reactions to such news took a somewhat odd turn in France in the spring of 2009 when workers at Sony France took the boss hostage for a night and barricaded their factory entrance with a tree trunk. He was freed only after he agreed to reopen talks on their severance packages. Similar incidents occurred at 3M and Caterpillar plants in France. A poll taken by Le Parisien in April 2009 found 45% of the French “supportive” of such action. A similar poll taken by Paris Match, April 2–3, 2009, found 30% “approving” and 63% were “understanding” or “sympathetic” of the action. Only 7% condemned the practice of “bossnapping.”

The Paris Match poll was based on a random representative sample of 1010 adults. What can we conclude about the proportion of all French adults who sympathize with (without supporting outright) the practice of bossnapping? Build and interpret (30 points) a 95% confidence interval for the proportion of all French adults who sympathize with the practice of bossnapping.
