Question
Please assist me in answering this simulation and modelling question
A company manufactures components for the computer industry and has developed a model of one of its production systems. The measure of interest is the time that a component has to wait in one of the processes. The production process operates 12 hours a day and the system starts each day in the empty state. The model was run 100 times and the mean times the component had to wait is 29.3 minutes with a standard deviation of 2.94 minutes. (i) Determine the 90% confidence interval for the true mean time from the model. (ii) Suppose the measurements from the real system gave a mean figure of 22 minutes, what would you conclude about the validity of the model?
