The following data pertain to usage at the computer lab for a business school.

The director of the computer lab wonders if this current usage pattern is the best use of the state-of€“the-art machines in the computer lab. She notes that students often stand in line for 15 minutes or more to check email for 5 minutes or to use course management software (e.g., blackboard or WebCT) to print the notes and other handouts (again, a 5-minute job). Finally, the director notes that machines that are several years old can easily accommodate these tasks. While the director has 20 to 30 of these old machines in storage, the computer lab does not have space to deploy them.
