1. A bank has two tellers working on the savings accounts. The first teller only handles withdrawals. The second teller only handles deposits. It has been found that the service time distribution for the deposits and withdrawals, both are exponential with mean service time 3 minutes per customer. Depositors are found to arrive in a Poisson fashion throughout the day with a mean arrival rate of 16 per hour. Withdrawers also arrive in a Poisson fashion with a mean arrival rate of 14 per hour. a. What would be the effect on the average waiting time for depositors and withdrawers if each teller could handle both the withdrawals and deposits? b. What would be the effect if this could only be accomplished by increasing the service time to 35 minutes?
