5. A new shopping mall is considering setting up an information desk manned by one employee. Based upon information obtained from similar information desks, it is believed that people will arrive at the desk at a rate of 20 per hour. It takes an average of 2 minutes to answer a question. It is assumed that the arrivals follow a Poisson distribution and answer times are exponentially distributed. (a) Find the probability that the employee is idle. (b) Find the...

1. A new shopping mall is considering setting up a car wash manned by six employees. From past data, Regal Car Wash estimates that dirty cars arrive at the rate of 10 per hour all day Saturday. With a crew working the wash line, Regal figures that cars can be cleaned at the rate of one every 5 minutes. One car at a time is cleaned in this example of a single-channel waiting line. It is assumed that arrivals are...

The school of business at abc university has a information desk manned by one student worker. It takes him an average of 3 minutes to answer questions raised by guests who visit the school building. Guests arrive at the desk at the rate of 15 per hour. Suppose that arrivals are Poisson and the service times are exponentially distributed. A. What is the average waiting time in queue? B. Suppose the worker earns $7.25 per hour. The cost of waiting...

A. A Medical Center is seeking the recruitment of a dentist for its outpatient clinic due to the high demand on dental services in the center. The center's records show that the patients arrive at the outpatient clinic at the rate of 8 per hour. The records also show that it takes an average of 6 minutes to checkup a patient. It is assumed that arrivals follow the Poisson distribution while the checking up times follow the negative exponential distribution....

An airline ticket counter has one line feeding into 2 ticket agents. The airline is considering adding a third agent. Arrivals are spaced at an average of 4 minutes, Poisson distribution. An agent spends about 5 minutes per customer, exponentially distributed. All other appropriate assumptions hold. Make sure you solve for the correct performance measure using the correct equations. Solving for an incorrect performance measure will result in zero points. Solving for more than one performance measure and not indicating...

A movie theater has four (4) auditoriums. Each of the four auditoriums plays a different film. The theater has a single ticket booth and a cashier who can maintain an average service rate of 280 movie patrons per hour. Patrons arrive at an average rate of 210 per hour and follow a Poisson distribution. Find the average number of moviegoers waiting in line to purchase a ticket. What percentage of the time is the cashier busy? What is the average...

Students arrive at the Administrative Services Office at an average of one every 12 minutes, and their requests take on average 10 minutes to be processed. The servicecounter is staffed by only one clerk, Judy Gumshoes, who works eight hours per day. Assume Poisson arrivals and exponential service times. Required: (a) Whatpercentage of time is Judy idle? (Round your answer to 2 decimal places. Omit the "%" sign in your response.) (b) How much time, on average, does a student...
