According to a study the average waiting time at the drive thru window at Mc Donald as measured from the time a customer places an order until the time a customer receives his order was 3.7 minutes. The franchise personnel believes that the average waiting time is not equal to 3.7 minutes. He wanted to institute a new process intended to reduce waiting time. A random sample of 25 orders were collected, and yields a mean waiting time of 3.84 minutes with a sample standard deviation of 0.4 minute. Test this claim at α = 0.05 level of significance. The type of testing is a; One tailed test to the right One tailed test to the left Two tailed test The computed value of t-test using the appropriate test statistic formula is; 1.50 1.57 1.75 The critical value to be used in comparing the computed value of the t-test statistic is; 1.645 1.708 1.711
