A growing concern of employers is time spent in activities likesurfing the Internet and e-mailing friends during work hours. TheSan Luis Obispo Tribune summarized the fundings from a survey of alarge sample of workers in an article that ran under the headline"Who Goofs Off 2 Hours a Day? Most Workers, Survey Says" (August 3,2006). Suppose that the CEO of a large company wants to determinewhether the average amount of waisted time during an 8-hour workday for employees of her company is less than the reported 120minutes. Each person in a random sample of 12 employees wascontacted and asked about daily waisted time at work. The resultingdata are the following:
108 112 117 128 130 111 131 116 113 113 105 128
The CEO wants to determine if these data provide evidence thatthe mean wasted time for this company is less than 120 minutes.Assuming that the population distribution is approximately normal,find the P-value for this test.
