1. Numbers are correct but put additional words, e.g. wrong: 10 units ->right: 10 2. Keep fewer than 3 digits after the decimal for infinite decimal numbers, e.g., wrong: 8.23 ->right: 8.231 3. Keep 3 digits after the decimal for finite decimal numbers, e.g., wrong: 8.000 ->right: 8

QUESTION:

Bill Youngdahl has been collecting data at the TU student grill. He has found that students arrive at the grill at a rate of 24 per hour and service time takes an average of 2 minutes (exponential distribution for both arriving time and service time). There is 1 server, who can work on only 1 order at a time. (Fill out number with three digits after the decimal for infinite numbers, for example, 0.123) What is the utilization rate? What is the average time a student is waiting in line for a burger? mins. What is the average number of students in the system? Suppose a second server is added and the 2 servers act independently, with each taking an average of 2 minutes. What would be the average time a student is waiting in line for a burger? mins
