Question 4 Not yet A local bank has generated the following metrics an arrival rate of 18 customers per hour with a service time of 3 minutes per customer and wait times Wq -0.45 hours for s. 1, Wq -0.0127 hours for s-2, and Wq -0.0017 hours for s. 3. The goal is to solve the following argument: argmin $75 - $4914. What is the total cost for s = 3? Marked out of 1.00 Flag question Select one: O a $22.47 b. 521 O c. 51.49 d. $0.08 Question 5 Not yet A local bank has generated the following metrics: an arrival rate of 18 customers per hour with a service time of 3 minutes per customer, and wait times Wq - 045 hours for s = 1, Wq = 0.0127 hours for s = 2, and Wq -0.0017 hours for s = 3. The goal is to solve the following argument: argmin $75 - $4914. What is the optimal service level? Marked out of 100 Select one: as = 1 Flag question Obs=2 Ocs-3 Question 6 Not yet answered Marked out of 1.00 A local bank has generated the following metrics, an arrival rate of 18 customers per hour with a service time of 3 minutes per customer, and wait times Wq -0.45 hours fors - 1, Wq=0.0127 hours for s = 2, and Wq = 0.0017 hours fors - 3. The goal is to solve the following argument: argmin $75 - $4919. Considering the optimal service level, what is the average time spent in the system? (Hint: calculate W and simply multiply by the conversion factor of 60). Flag question Select one: a. 2 minutes b. 3.2 minutes O c. 5.3 minutes d. 11.1 minutes
