After Pooling Q2 Consider the same urgent care center with 4 doctors where the average arrival rate for each doctor is 24 patients per hour and the average service time of each patient is 2 minutes. Both inter-arrival times and service times have a coefficient of variation equal to one. But now, the doctors are pooled so that a doctor can serve any patient. After pooling, what is the average number of patients in the clinic (including those waiting in line to see a doctor as well as those who are seeing a doctor)? Recall there is only one common queue after pooling and round your answer to two decimal points.
