Refer to Exercise 11.61.

a. Calculate the predicted response time if there is a backlog of four customers.

b. Place a 95% prediction interval on your prediction in part (a).

c. Compute a 95% confidence interval on the mean response time for situations where there is a backlog of four customers. Compare this interval to the interval computed in part (b).

d. What is the difference in interpretation of the two intervals computed in parts (b) and (c)?

e. The manager has requested an estimate of the mean response time if there was a backlog of seven customers. What is the problem with producing the estimate?
