Suppose a mean of 20 customers arrive at the drive-through
windows at a bank each hour. If
each bank teller can handle 6 customers per hour, how many tellers
are needed so that the
probability all customers can be served in the hour is at least
0.95?

Cars arrive at a rate of 10 per hour in a single-server drive-in restaurant. Assume that the teller serves vehicles with a rate exponentially distributed with a mean of 4 minutes per car (ie, a rate of 1 car every 4 minutes). Answer the following questions: (a) What is the probability that the teller is idle? (b) What is the average number of cars waiting in line for the teller? (A car that is...

Customers arrive at bank according to a Poisson process with rate 20 customers per hour. The bank lobby has enough space for 10 customers. When the lobby is full, an arriving customers goes to another branch and is lost. The bank manager assigns one teller to customer service as long as the number of customers in the lobby is 3 or less. She assigns two tellers if the number is more than 3 but less than 8. Otherwise she assigns...

A bank has one drive-up teller. The teller can serve at the rate of 11.2 bank customer in an hour. Customers arrive at the drive-up window on an average every 7.5 minutes. The bank is currently analyzing the possibility of adding a second drive-up window at an annual cost of $20,000. It is assumed that arriving cars would be equally divided between both windows. It is estimated that each minute’s reduction in customer waiting time would increase the bank’s revenue...

Customers arrive at a bank that has 1 teller and they wait in line on a first-come, first-sorved basis. Customers arrive according to a Poisson process with a rate of 14.5 per hour. It takes on average 4 minutes for a customer to be served by the tellor. No customer leaves without going through service with the teller. The standard deviation of the service time is 2 minutes. What is the average time a customer spends waiting in line? (Enter...

Example 1 Follow National Bank FNB operates a drive-up teller window that allows customers to complete bank transactions without getting out of their cars. On weekday mornings cars arrive randomly with a mean arrival rate of 24 customers per hour (0.4 per minute) What is the expected number of customers that will arrive in a 5-minute period? Delays are expected if more than 3 customers arrive during any 5-minute period. What is the probability that delays will occur? Assume that...

Problem 15-1 Willow Brook National Bank operates a drive-up teller window that allows customers to complete bank transactions without getting out of their cars. On weekday mornings, arrivals to the drive-up teller window occur at random, with an arrival rate of 24 customers per hour or 0.4 customers per minute. What is the mean or expected number of customers that will arrive in a five-minute period? λ = per five minute period Assume that the Poisson probability distribution can be used...

The amount of time that a drive-through bank teller spends on a customer is a random variable with a mean 3.2 minutes and a standard deviation a = 1.6 minutes. If a random sample of 64 customers is observed, find the probability that their mean time at the teller's window is A. at most 2.7 minutes; B. more than 3.5 minutes; C. at least 3.2 minutes but less than 3.4 minutes (10 pts. each, 30 pts. total)
