Pick one answer per question. Explanations appear after you submit.

1. 1. 1,200 units, each with 8 opportunities, 60 defects total. DPO is:

   • 0.006
   • 0.00625
   • 0.05
   • 0.075

2. 2. Which is discrete data?

   • Seam strength (N)
   • Number of stitches per inch
   • Fabric shade delta-E
   • Sleeve length (mm)

3. 3. Cp = 1.33 and Cpk = 0.5 mean:

   • Process is capable
   • Spread is fine but the mean is far off-centre — defects come from location
   • MSA is bad
   • Specification is wrong

4. 4. Sampling only during the day shift to represent the whole line is:

   • Random
   • Convenience/biased
   • Stratified
   • Systematic

5. 5. A check sheet's first requirement is:

   • Colour coding
   • A shared operational definition of what to count
   • A senior signature
   • A digital app

6. 6. Pareto plots are useful when:

   • Data is continuous
   • A few defect categories dominate the count
   • Data is normal
   • Sample is small

7. 7. Resolution 5 mm on ±2 mm tolerance is:

   • Adequate
   • Inadequate — resolution should be roughly 1/10 of tolerance
   • Adequate with two inspectors
   • Adequate after calibration

8. 8. Attribute agreement analysis tests:

   • Machine reliability
   • Whether appraisers classify items consistently and correctly
   • Statistical significance
   • Fabric strength

9. 9. Yield of a process making 1,000 units with 40 defective units is:

   • 100%
   • 96%
   • 94%
   • 60%

10. 10. Capability calculation on an unstable process is:

    • Encouraged
    • Meaningless until stability is achieved
    • Standard
    • Required by SPC
