The pharmacist at Arnold Palmer Hospital, Wende Huehn-Brown, receives 12 requests for prescriptions each hour, Poisson distributed. It takes her a mean time of 4 minutes to fill each, following a negative exponential distribution. Use the waiting line table, Table D.5, and W q 5 L q > λ, to answer these questions.
a) What is the average number of prescriptions in the queue?
b) How long will the average prescription spend in the queue?
c) Wende decides to hire a second pharmacist, Ajay Aggerwal, with whom she went to school and who operates at the same speed in filling prescriptions. How will the answers to parts (a) and (b) change?
