8. At the emergency department of BPH, nurses triage patients to determine the severity of their condition and establish the order in which they should be seen by the doctors. From 6:00 a.m. to 10:00 a.m., an average of 18 patients needing this service arrive per hour. Assume Poisson rates and exponential times. BPH is considering the following three alternatives: - Three nurses do the triage, separately. Each nurse averages 7 minutes with a patient. - Four medical assistants do the triage, separately. Each one has an average service time of 12 minutes. - One nurse and two medical assistants work as a team with an average service time of 3 minutes. The nurses are paid $50.00 per hour, the medical assistants are paid $35 an hour, and the patient time in the triage area is valued at $60.00 an hour. Which system would you recommend
