The mаnаger оf Wаsh Me car-wash center has built a simulatiоn mоdel 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. In order to reduce Wash-Me’s average cycle time, an improved system has been proposed and simulated. After 10 simulation runs, the new system’s average cycle time has a sample mean of 25 min and a standard deviation of 12 min. The manager would like to conduct a proper hypothesis test to see if the new system is better than the old system at 10% significance level. Suppose that the manager runs 9 more simulations for both the old and new system and then use Excel to perform a t-test with 5% significance level. What conclusion can you draw from Excel output (see below; also available from ttest.pdf)?
