QUESTION 21 A manufacturing operation consists of a single machine-tool system that produces an average of 15.5 transformer parts per hour. After undergoing a complete overhaul, the system was monitored by observing the number of parts produced in each of 17 randomly selected one-hour periods. The sample mean - 15.42 and the sample standard deviation - 0.16 for the sample of n-17 production runs. Does the sample provide sufficient evidence to conclude that the true mean number of parts produced...
