Need to solve using Excel Queuing System
From historical data, Harry's car wash estimates that dirty cars arrive at the rate of 10 per hour all day Saturday. With a crew working the wash line, Harry figures that cars can be cleaned at the rate of one every five minutes. One car at a time is cleaned in this example of single-server waiting line. Assuming Poisson arrivals and exponential service times, find the
A) average number of cars in line
B) average time a car waits before it is washed
C) average time a car spends in the service system
D) utilization rate of the car wash
E) probability that no cars are in the system
