(Process Performance Measures) A loan processing office receives 4 loan requests every hour. The office has 2 departments. It takes the first department on average 20 minutes to do a preliminary check on the requests and 20% are rejected directly without going into the second department. The remaining 80% go into the second department and take 60 minutes per request and then either an acceptance or rejection letter is sent to the client. On average how many requests are in the first department (including those who are waiting)? How many are in the second (including those who are waiting)? (Hint: Since this question does not specify how many servers are in each department, please do not assume that there is only one server. Instead, you may use the Little’s Law here.)
