An automobile dealer is planning a new custom service center to repair the microcomputer-based engine controls in new-model cars.

Preliminary estimates suggest that about 5 customers will bring their cars for repair each day. To analyze this situation, make the following assumptions: The customer arrivals form a Poisson process. Each job requires on average 75 minutes.
