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 computed value of the test statistic lies in the; Rejection area Acceptance area None of the above the interpretation of the data based from the results is; Statistically significant Not statistically significant None of the above
