Example (Typical from Mahajan’s exercises)

Problem:
20 samples of size 5 each gave (\bar\barX = 40.2) mm and (\barR = 0.8) mm. Compute control limits for X̄ and R charts. Given for n=5: A₂ = 0.577, D₃ = 0, D₄ = 2.115.

4. Acceptance Sampling: The Science of Inspection

Unlike 100% inspection, which is expensive and prone to inspector fatigue, Acceptance Sampling uses probability to make decisions. Mahajan outlines key plans, including:

Conclusion

Statistical Quality Control by Mahajan remains a cornerstone text because it strips away the mystique of quality management. It demonstrates that quality is a quantifiable metric governed by the laws of probability. Let me know if you want me to make any changes

If a machine cannot physically hold the tolerance required, no amount of control charting will fix the problem. The process must be redesigned.
