The respоnse time оf а distributed cоmputer system is аn importаnt quality characteristic. The system manager wants to know whether the mean response time to a specific type of command exceeds 75 milliseconds. From experience, she knows that the response time is approximately normally distributed, with a standard deviation of 8 milliseconds. The command is executed 25 times and the response times are recorded (n = 25). Which statistical test should be used to determine whether the mean response time is greater than the historical value of 75 millisec?
