In the robotic fulfillment exercise, we found that the optimal ratio of the number of robots to the number of workers was 8:1. Which of the following statements correctly describes the consequences of deviating from this ratio; i.e, from having too many or too few robots? Group of answer choices The fulfillment cost will increase because either the workers or the robots will be underutilized. The productivity will decrease if there are too few robots and increase if there are more than eight robots per worker. The more robots, the better it is for higher productivity. The fulfillment cost will increase if there are too few robots and decrease if there are more than eight robots per worker
