Suppose the management is thinking of replacing the human cashier by an electronic checkout process that will have exactlysameservice rate but now it will have aconstant service time. So, essentially remainsthe same, except it is constant now.

(3)The average length of theline of "waiting customers" in this arrangement is =people (round to two places of decimal)

(4)The average waiting time for a customer before starting the checkout process =minutes(round to two places of decimal)
