This pandemic, PCI Bank opens a drive-thru window for customers to complete bank transactions without getting out of their cars. Arrivals occur at random, with an arrival rate of 30 customers per hour. a. What is the mean or expected number of customers that will arrive in a five- minute period? b. Assume that the Poisson probability distribution can be used to describe the arrival process. Compute: i. the probability that exactly 0 will arrive during a five-minute period ii. the probability that exactly 2 will arrive during a five-minute period

Pete's Market is a small local grocery store with only one checkout counter. Assume that shoppers arrive at the checkout lane according to a Poisson probability distribution, with an arrival rate of 20 customers per hour. The checkout service times follow an exponential probability distribution, with a service rate of 25 customers per hour. The manager’s service goal is to limit the waiting time prior to beginning the checkout process to no more than five minutes. Also the manager of Pete's Market wants to consider one of the following alternatives for improving service. Calculate the value of Wq for each alternative. Hire a second person to bag the groceries while the cash register operator is entering the cost data and collecting money from the customer. With this improved single-server operation, the service rate could be increased to 33 customers per hour. Round your answer to three decimal places. Do not round intermediate calculations.Wq = 2.797 minutes Hire a second person to…
