Long lines of patients wait for CAT scanning service in a hospital.  Patients arrive for scans at a rate of 1.8 per hour. The average processing time for CAT service is 27 minutes per patient. Your summer internship is in the hospital where you are assigned to help analyze the bottleneck situation. One tool that you think can help evaluate the situation is a single server queueing model. Use the Single Server Queue Excel template to answer the following questions:

a. What is the probability that the system is empty?

b. What is the probability that a customer must wait for service?

c. What is the average number of customers waiting for service in the queue?

d. What is the average wait time in the queue?

e. What is the average time spent in the system?

f. Given these results, what might be your recommendations?
