Customers checking out at Food Mart arrive in a single-line queue served by two cashiers at a rate of eight per hour according to a Poisson distribution. Each cashier processes customers at a rate of eight per hour according to an exponential distribution. 1. If, on average, customers spend 30 minutes shopping before getting in the checkout line, what is the average time a customer spends in the store? 2. What is the average number of customers waiting for service in the checkout line? 3. What is the probability that a customer must wait? 4. What assumption did you make to answer this question? I need this in Excel format please. Can you also include a small interpretation with the answers ?
Please do not give solution in image format thanku
