A manufacturing plant records the defect rates for three production lines (P1, P2, P3) over four quarters. The table shows the number of units produced and the percentage of defective units. If the plant manager wants to prioritize improving the line with the highest *absolute number* of defective units in Q3, which line should be chosen?
✓ Correct Answer: Option B
In Q3: P1: 4000 units * 2.5% = 100 defects. P2: 3000 units * 4.0% = 120 defects. P3: 5000 units * 1.5% = 75 defects. Line P2 has the highest absolute number of defective units (120).
