Ford Motor Company was concerned that five tug operators, each costing $100,000 annually over three shifts, was too many. Colin Cruji was hired to look into the tug operators and see if Ford could eliminate one or more of the five positions per shift. Colin has now collected some data. How should he use the data he has collected to evaluate the position of tug operator? Does the data support the possibility of eliminating a tug operator without affecting the current level of garbage collection? (This is a sequel to Ford Motor Company and Cruji Management Consulting (A), case 9A99E013.)
