8)- The effect of machine breakdowns on the performance of a manufacturing system was investigated using computer simulation (Industrial Engineering, August 1990). The simulation study focused on a single machine tool system with several characteristics, including a mean interarrival time of 1.25 minutes, a constant processing time of 1 minute, and a machine that breaks down 10% of the time. After n = 5 independent simulation runs of length 160 hours, the mean throughput per 40 hour week was sample mean = 1,908.8 parts. For a system with no breakdowns, the mean throughput for a 40 hour week will be equal to 1920 parts. Assuming the standard deviation of the 5 sample runs was s = 18 parts per 40 hour week, test the hypothesis that the true mean throughput per 40 hour week for the system is less than 1920 parts. Test using a = 0.05.
