A manager is contemplating making changes to a single-server system that is expected to double the service rate, and still have just one server. For the sake of analysis, suppose the current system has an arrival rate of 8 customers per hour and a service rate of 10 customers per hour. If the service rate is doubled, find the impact that this would have on the average number of customers waiting in line. Compute the following ratio:

L_q2 / L_q1 = ? (Two decimal points)

L_q1 is the average number of customers waiting in line if the service rate doesnt change.

L_q2 is the average number of customers waiting in line if the service rate doubles.
