1 (5 points). Consider the same hospital emergency room example from the lecture notes on preemptive priority protocol. Assume an exponential distribution model with a mean of 2 arrivals per hour with 10%, 30%, 60%, respectively, for patients classified as (i) critical case, (ii) serious case, (iii) stable case. To save cost, the hospital wants to know what is expected waiting time in queue for each class of patients if the hospital can increase the mean service rate to = 4 patients per hr by staffing only one doctor but with some additional technical assistance to the doctor, again assuming exponential distribution for service completion time
