The correct answer is: Before pooling: 8.3 customers, after pooling: 3.8 customers, so decrease of 4.5 customers.

Question 3 1 pts By how much, on average, would the total number of customers (the sum of those in all queues plus those in all servers) change if two servers were pooled in the following setting (note: all answers are rounded to whole minutes): 1) Before pooling, there are two servers each with their own queue. 2) Each server has an arrival rate of 5 customers per hour, arriving randomly. 3) Each server has a processing time of 10 minutes per customer, with a standard deviation of 10 minutes. Remember, the question is asking about the TOTAL number of customers in all queue(s) plus those in all servers. Before pooling: 8.3 customers, after pooling: 3.8 customers, so decrease of 4.5 customers Before pooling: 4.2 customers, after pooling: 3.8 customers, so decrease of 0.4 customers Before pooling: 5 customers, after pooling: 5.5 customers, so increase of 0.5 customers Before pooling: 5.2 customers, after pooling: 2.4 customers, so decrease of 2.8 customers Question 3 1 pts By how much, on average, would the total number of customers (the sum of those in all queues plus those in all servers) change if two servers were pooled in the following setting (note: all answers are rounded to whole minutes): 1) Before pooling, there are two servers each with their own queue. 2) Each server has an arrival rate of 5 customers per hour, arriving randomly. 3) Each server has a processing time of 10 minutes per customer, with a standard deviation of 10 minutes.
