1. What is the primary purpose of sampling in inspection
procedures?
A. To inspect every item produced
B. To reduce production speed
C. To evaluate a portion of a lot to infer quality of the
whole
D. To eliminate inspection requirements
Correct answer: C
Rationale: Sampling is used to assess a subset of items to draw
conclusions about the entire population efficiently without full
inspection.
, 2. Which inspection method involves checking every single
unit in a lot?
A. Random sampling
B. 100% inspection
C. Acceptance sampling
D. Stratified sampling
Correct answer: B
Rationale: 100% inspection means every item is examined
individually rather than selecting a sample.
3. What does AQL stand for in quality inspection?
A. Average Quality Level
B. Acceptable Quality Limit
C. Acceptable Quality Level
D. Actual Quality Loss
Correct answer: C
Rationale: AQL refers to the maximum number of defective
items considered acceptable in a sample.
4. In sampling inspection, a “lot” refers to:
A. A single defective product
B. A batch of items produced under similar conditions
, C. A quality certificate
D. An inspection tool
Correct answer: B
Rationale: A lot is a defined quantity of products
manufactured or processed under similar conditions.
5. Which factor most influences sample size in inspection?
A. Color of product
B. Production supervisor preference
C. Lot size and inspection level
D. Packaging style
Correct answer: C
Rationale: Sample size is determined mainly by lot size and the
chosen inspection level or standard.
6. What is the main advantage of acceptance sampling?
A. It eliminates defects entirely
B. It reduces inspection time and cost
C. It increases production speed
D. It guarantees zero defects
Correct answer: B
Rationale: Acceptance sampling saves time and cost by
inspecting only a portion of the lot.
, 7. A random sample means:
A. Selected based on inspector preference
B. Selected using a systematic pattern
C. Every item has an equal chance of selection
D. Only defective items are chosen
Correct answer: C
Rationale: Random sampling ensures each item has an equal
probability of being selected, reducing bias.
8. What happens if a sample fails inspection under
acceptance sampling?
A. Entire lot is automatically accepted
B. Entire lot is rejected or subjected to further inspection
C. Production stops permanently
D. Only the sample is discarded
Correct answer: B
Rationale: Failure in sample inspection typically results in lot
rejection or 100% inspection.
9. Which inspection level typically requires a larger sample
size?
A. Reduced inspection level
