Use the fоllоwing infоrmаtion to аnswer Questions 24-30. The mаnager 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. Answer Questions 26-28 also considering the following information 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. The conducted hypothesis test provided a p_value of 0.7. What decision can you draw from it?
