   2. lower than the AQL.

   3. conclusive.

   4. inconclusive.

2. When is the 100% inspection done?

   2. The suppliers process is so bad that almost every unit is defective

   3. Thecomponentisextremelycritical

   4. The component is moderately critical

3. Three random pieces are selected from a lot having 3% defective. What is the probability that there are exactly 3 defectives in this selection?

4. The acronym "RQL" as used in sampling insepection means:

   1. That level of lot quality for which there is a small risk of rejecting the lot.

   2. The average outgoing quality level.

   3. Worst tolerable process average

   4. Quality level that is unacceptable to the customer

5. Acceptance sampling is not used when ___

   1. The test is destructive

   2. The cost of 100% inspection is quite high

   3. The suppliers process capability is very high

   4. Although the supplier process is satisfactory but a program is needed for continuous monitoring

6. The no-inspection alternative of sampling is used when ____

   1. The component is extremely critical

   2. The component is moderately critical

   3. The suppliers process is so good that defective units are never encountered

7. Which of these would decrease the probability of making a Type II error?

   1. increasing the sample size

   2. reducing the fraction defective

   3. increasing the AQL

   4. reducing the LTPD

8. The fraction defective below which we would prefer there to be a very high probability of acceptance is the:

   1. average outgoing quality rate.

   2. lot tolerance percent defective.

   3. acceptable quality level.

   4. Type I error rate.
