In 2006, the average U.S. production employee worked 38.9 hours per week. An assistant in the human resources department of Acme Eyebolts, Inc., is curious as to how the workers in her company compared to this figure during the first week of this month. The assistant will be reaching her conclusions based on a simple random sample of 30 data values out of the 300 Acme workers’ weekly hours listed in file XR04073. Help the assistant by generating the simple random sample and computing its mean. Based on the sample, compare the Acme workweek with that of production workers nationally.
