Question 7 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 fors - 3. The goal is to solve the following argument: argmin $7s + $49.4. Considering the optimal service level, what is the average number of people in the system? answered Marked out of 1.00 Flag question Select one: O a. 0.41 O b. 0.95 O c. 2.73 d. 3.33 Question 8 Not yet answered 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 - $49.4. Considering the optimal service level, what is the system cycle time? (Hint calculate CT and simply multiply by the conversion factor of 60). Marked out of 1.00 P Flag question Select one: O a 3.33 minutes b. 1.5 minutes O c. 1 minute O d. 0.5 minutes Question 19 Not yet Consider the M/M/s system below with metrics for s-2 and s. 3.
