Waiting Lines Homework Question 5, Problem D.11, HW Score: 10%,10 of 100 points a) The average number in the line = customers (round your response to two decimal places). a) The average number in the line =3.20 customers (round your response to two decimal places). b) The average time in the system = minutes (round your response to one decimal place). c) Suppose that a second server can be added to team up with the first (and, in effect, act as one faster server). This would reduce the average service time to 90 seconds. The average time in the system =3.75 minutes (round your response to two decimal places). d) Suppose a second server is added and the 2 servers act independently, with each taking an average of 2.0 minutes. If a second server is added, the average time a customer spends in the system = minutes (round your response to two decimal places)
