Acceptance Sampling MCQs : This section focuses on the "Acceptance Sampling" in Statistical Quality Control. These Multiple Choice Questions (MCQs) should be practiced to improve the Statistical Quality Control skills required for various interviews (campus interview, walk-in interview, company interview), placement, entrance exam and other competitive examinations.
______________ uses statistical sampling to determine whether to accept or reject a production lot of material
A. Systematic sampling
B. Acceptance sampling
C. Stratified sampling
D. Clustered sampling
Explanation: Acceptance sampling uses statistical sampling to determine whether to accept or reject a production lot of material.
Acceptance sampling procedures became common during World War II.
C. Can be yes or no
D. Can not say
Explanation: Acceptance sampling procedures became common during World War II. Sampling plans, such as MIL-STD-105, were developed by Harold F. Dodge and others and became frequently used as standards.
Acceptance sampling is employed when?
A. testing is destructive
B. the cost of 100% inspection is very high
C. 100% inspection takes too long
D. All of the above
Explanation: In general, acceptance sampling is employed when one or several of the following hold: testing is destructive, the cost of 100% inspection is very high; and 100% inspection takes too long.
AQL stands for?
A. average quality limit
B. acceptable quality limit
C. acceptable quantity limit
D. average quantity limit
Explanation: Plans have known risks: an acceptable quality limit (AQL) and a rejectable quality level, such as lot tolerance percent defective (LTDP), are part of the operating characteristic curve of the sampling plan.
Which of these is not a correct statement for Acceptance Sampling?
A. Concerned with inspection of products
B. Concerned with decision making regarding products
C. One of the oldest aspects of quality assurance
D. One of the oldest aspects of quality control
Explanation: Acceptance sampling is a procedure used in quality assurance, which is concerned with inspection of manufactured products and the decision making regarding their state.
Which of these is not an advantage of acceptance sampling over the 100% sampling plan?
A. Less expensive
B. Applicable to destructive testing
C. Highly costly
D. Lesser manpower is needed
Explanation: As lesser number of units are checked while using the acceptance sampling plan instead of the 100% sampling plan, it is less expensive, applicable to destructive testing, and needs lesser manpower.
Sequential sampling is an extension of ____________
A. Single sampling plan
B. Double-sampling plan
C. Multiple-sampling plan
D. 0% sampling
Explanation: As the multiple-sampling plan is associated with the case when N numbers of samples are taken of n units, it has an intimate extension as Sequential sampling.
Acceptance sampling can be used as _____________
A. Incoming inspection activity
B. Outgoing inspection activity
C. Neither incoming nor outgoing inspection activity
D. Both, incoming and outgoing inspection activity
Explanation: The Acceptance sampling is customarily thought to be the receiving or incoming inspection activity, but there are a few cases where it can be used as the outgoing inspection activity.
Which of these requires planning and documentation of the sampling procedure?
A. Acceptance sampling
B. 100% sampling
C. 0% sampling
D. 50% sampling
Explanation: The 100% sampling checks the whole lot, so it does not require any planning or documentation, whereas the acceptance sampling requires it.
100% inspection does not guarantee 100% compliance.
C. Can be true or false
D. Can not say
Explanation: True, 100% inspection does not guarantee 100% compliance and is too time consuming and costly.
