How many patients, on average, are in the waiting area? a. 8.1 patients b. 2.25 patients c. 3.2 patients d. 0.9 patients An urgent care center is analyzing its waiting area for patients. There is one doctor that takes an average of E[T]=6 minutes to treat a patient. Data shows that arrivals are =8 per hour, on average, with both the interarrival times and service times following an exponential distribution. To determine the efficiency of the current operation, the manager wishes to examine several queue operating characteristics. What is the probability distribution of the interarrival time, A? a. A Exponential(4) b. A Exponential(6) c. A Exponential(8) d. A Exponential(10) Clear my choice
