Question related to queing theory don't copyA bank has two tellers working on savings accounts. The first teller handles withdrawals onlywhile the second teller handles depositors only. It has been found that the service timedistributions of both depositors and withdrawals are exponential with a mean service time of5 minutes per customer. Depositors and withdrawers are found to arrive in a Poissondistribution throughout the day with mean arrival rate of 12 and eight per hour,respectively. What would be the effect on the average waiting time for depositors andwithdrawers if each teller could handle both withdrawals and depositors? What would be theeffect if this could only be accomplished by increasing the service time to four minutes?

Given - Depositor Arrival Rate =12 per hr Withdrawer Arrival rate= 8 per hr Service rate = 5 min per…

DEMU 2103, va assignmen QUESTION 3 Metropolitan General Hospital is a city-owned and operated public hospital. Its emergency. room is the largest and most prominent in the city. Approximately 70% of emergency cases in the city come or are sent to Metro General's emergency room. As a result, the emergency room is often crowded and the staff is overworked, causing concern among hospital administrators and city officials about the quality of service and health care the emergency room is able to provide. One of the key quality attributes administrators focus on is patient waiting time that is, the time between when a patient checks in and registers and when the patient first sees an appropriate medical staff member. Hospital administration wants to monitor patient waiting time using statistical process control charts. At different times of the day over a period of several days, patient waiting times were recorded at random with the following results: Sample 1 2 3 4 5 6 7 8 9 10 1 27 22 16…
