Swift Transportation Co., Inc.

9-60. Swift is the holding company for Swift Transportation Co., Inc., a truckload carrier headquartered in Phoenix, Arizona. Swift operates the largest truckload fleet in the United States. Before Swift switched to its current computer-based billing system, the average payment time from customers was approximately 40 days.

Suppose before purchasing the present billing system, it performed a test by examining a random sample of 24 invoices to see if the system would reduce the

average billing time. The sample indicates that the average payment time is 38.7 days.

a.     The company that created the billing system indicates that the system would reduce the average billing time to less than 40 days. Conduct a hypothesis test to determine if the new computer- based billing system would reduce the average billing time to less than 40 days. Assume the standard deviation is known to be 6 days. Use a significance level of 0.025.

b.    If the billing system actually reduced the average billing time to 36 days, determine the probability that a wrong decision was made in part a.
