O 1 O2 3 What is the corresponding wait time in the system in minutes? Adding another barber can be expensive for Marty's. Select another way that can improve the operating charactersistics? O Decrease the service rate. O Increase the arrival rate. Increase the service rate by having the cashier sweep up the hair in between O None of the above.
