PREVIOUS ANSWERS ASK YOUR TEACHER PRACTICE ANOTHER Many employers are concerned about employees wasting time by surfing the Internet and e-mailing friends during work hours. The article "Who Goofs Off 2 Hours a Day? Most Workers, Survey Says" summarized data from a large sample of workers.I Suppose that the CEO of a national marketing firm wants to determine the difference in mean wasted time during an 8-hour workday for employees of her company at two different locations. Each person in a random sample of 10 employees from Location A (population 1) is asked about daily wasted time at work (in minutes), and 10 employees from Location B (population 2) are asked the same question. Participants were guaranteed anonymity to obtain truthful responses. Suppose the resulting data are as follows. Location A 134 149 109 122 135 120 125 150 Location B 108 104 112 115 102 103 18 117 105 100 LO USE SALT (a) Calculate the point estimate for the difference in the population means. 9.9 X Find the average of each data set.
