A manufacturing company is evaluating three new production processes (X, Y, Z) to reduce defect rates. They must select one process and one training module (Basic, Advanced) for employees. The projected defect reduction (in percentage points) for each combination is shown below: | Process \ Training | Basic | Advanced | |--------------------|-------|----------| | X | 8 | 12 | | Y | 10 | 15 | | Z | 7 | 11 | Each process has an implementation cost: X=$50k, Y=$70k, Z=$40k. Each training module also has a cost: Basic=$10k, Advanced=$20k. The goal is to achieve the highest defect reduction for a combined cost not exceeding $90k. Which combination should be chosen?
✓ Correct Answer: Option B
A: Cost $50k+$20k=$70k (<= $90k). Reduction 12%. B: Cost $70k+$10k=$80k (<= $90k). Reduction 10%. C: Cost $70k+$20k=$90k (<= $90k). Reduction 15%. D: Cost $40k+$20k=$60k (<= $90k). Reduction 11%. Option C (15% reduction) is the highest within the budget.
