Data :

Students in the college of business must have their courses approved by the college adviser during registration at a large university. It takes the adviser an average of 2 minutes to approve each schedule, and students arrive at the advisers office at the rate of 29 per hour. Assume interarrival and service times are from the exponential distribution. Do this problem twice: once using formulas, and once using q.xls. a. Compute L,Lq,W,Wq, and U.b. The dean of the college has received a number of complaints from students about the length of time they must wait to have their schedules approved. The dean feels that waiting an average of 7 minutes to get a schedule approved (including service) is not unreasonable. Each assistant the dean assigns to the advisers office will reduce the average time required to approve a schedule by 0.25 minute, down to a minimum time of 1.00 minute to approve a schedule. How many assistants should the dean assign to the adviser?

Below is what I want you to answer: you can answer the top too if you don't mind

In 2, the dean of the college of business at State University is considering the addition of a second adviser in the college advising office to serve students waiting to have their schedules approved. This new adviser could serve the same number of students per hour as the present adviser. Determine L,Lq,W, and Wq for this altered advising system. Would you take the approach in problem 2, or problem 3 to reduce waiting times?
