The managers of the Grand Hotel are evaluating the possibility of setting up a computer area where conference attendees can check their e-mail on computers provided by the conference organizers. There will be one common queue for all computers, and only one person uses a computer at a time. On average there are 12 attendee arrivals per hour, and the standard deviation of the time between arrivals is 2.5 minutes. The average time that a person spends on the computer is 20 minutes, with a standard deviation of 10 minutes.
Suppose the organizers decide to install 5 computers. GH1. What is the average utilization of the 5 computers?
GH2. What is the expected time (in minutes) that an attendee will have to wait for a computer to become available?
