Herewith the reasons why 100% sampling cannot be implemented, except:

• The testing method is destructive test

• The total production amount is large

• To save inspector time

• To accommodate inspector who is lazy

Why Quality Control should be supported by Quality Assurance?

• A.      Quality cannot only be determined by the final inspection (Quality Control)

• B.      Quality needs to build into the product starting from the beginning

• C.       A&B incorrect

• D.      A&B correct

Good sampling method should accommodate the following principles:

• Sample must represent the population

• Sampling needs to be done randomly

• Sampling method should be standardize

• All is incorrect

When the source of the incoming raw material is recognized and the raw material is considered as uniform, then the appropriate sampling plan is:

• p-plan
• AQL
• n-plan
• r-plan

Sampling equipment that could be used the sample Raw Material is as follows:

• None are correct
• Only Pipettes
• All are correct
• Only Spatula

AQL can be used to determine below, except

• Number of inspectors that should be assigned
• Acceptance criteria based on number of defects found
• Accuracy level of the sampling process
• Number of samples to be taken

Herewith is the correct level of AQL

• Level I, II, III, IV, S1, S2, S3
• Level I, II, III, IV, S1, S2, S3, S4, S5, S6
• Level I, II, III, S1, S2, S3, S4
• Level I, II, III, IV, S1, S2, S3, S4, S5

When the product sampling could not meet the acceptance criteria, the following should be done:

• Another sampling activity can be conducted until the lot can be accepted
• All is incorrect

• Final disposition = rejected

• Another sampling activity can be conducted once

In the Operating Characteristic Curve, α (alpha) is risk from:

• None is correct
• Both side
• Supplier / producer side
• Consumer side

How to achieve an Ideal OC Curve?

• Conducting 100% Inspection
• Reducing supplier/producer’s risk
• Increasing consumer’s risk
• Conducting random sampling
