Benny the Barber owns a one-chair shop. At barber college, they told Benny that his customers would exhibit a Poisson arrival distribution and that he would provide an exponential service distribution. His market survey data indicate that customers arrive at a rate of 2.0 per hour. It will take Benny an average of 22 minutes to give a haircut. Based on these figures, find the following:The average time a customer waits?

1) A toll plaza has 5 booths, with each booth capable of servicing 50 cars per hour. Cars arrive at the plaza at the rate of 225 cars per hour. Make the standard assumptions of a Poisson distribution for arrivals, and an Exponential distribution for service times, and calculate the following: a) What is the probability of zero cars in the toll plaza? b) What is the average length (in cars) of the (total) queue?

Star Car Wash estimates that dirty cars arrive at the rate of 15 per hour all day and at the wash line, the cars can be cleaned at the rate of one every 4 minutes. One car at a time is cleaned in this example of a single-channel waiting line. Assuming Poisson arrivals and exponential service times, find the: (a) average time a car spends in the service system. (b) average number of cars in line. (c) average time a...

7. The Canara Bank drive-thru teller window can serve a customer at an average of 4 minutes per customer. Service time has a negative exponential distribution. Customers arrive in their cars at a rate (Poisson distributed) of 12 per hour and form a single waiting line: a. Determine the average waiting time, the average queue length, and the probability that there is no customer in the system. b. If Canara Bank decides to open a second drive-thru teller window with...

Question Three (4) Dell Eatery employs one worker whose job it is to load apple pies on outgoing company cars. Cars arrive at the loading gate at an average of 48 per day, or 12 per hour, according to a Poisson distribution. The worker loads them at a rate of 16 per hour, following approximately the exponential distribution in service times. a. Determine the operating characteristics of this loading gate problem. b. What is the probability that there will be...
