The Hair Port is a hair-styling salon at Riverside Mall. Four stylists are always available to serve customers on a first-come, first-served basis. Customers arrive at an average rate of four per hour (Poisson distributed), and the stylists spend an average of 45 minutes (exponentially distributed) on each customer.
a. Determine the average number of customers in the salon, the average time a customer must wait, and the average number waiting to be served.
b. The salon manager is considering adding a fifth stylist. Would this have a significant impact on waiting time?
