Use the following information to answer Questions 24-30. The manager of Wash Me car-wash center has built a simulation model to simulate and analyze the center’s service processes. Based on 10 simulation runs, the manager calculates that the average cycle time has a sample mean of 30 min and a standard deviation of 10 min. Please answer the following questions. If the manager would like to reduce the width of 95% confidence interval to less than 10 min, at least how many more simulation runs would be needed? (Consider a critical value of 1.96)
