B)  after two samples are taken. 
C)  after three or more samples are taken. 
D)  all of the choices. 
E)  none of the choices.

B)  after two samples are taken. 
C)  after three or more samples are taken. 
D)  all of the choices. 
E)  none of the choices.

Question 5

A)  lot size. 
B)  sample size. 
C)  number of samples to be taken. 
D)  acceptance/rejection criteria. 
E)  all choices are correct. 
A)  lot size. 
B)  sample size.

Question 7

Acceptance sampling is a form of inspection applied to items during an ongoing process.

Accepted Answer

A) True 
 B)False

Question 8

Acceptance sampling is applied to batches of items during the production process.

Accepted Answer

A) True 
 B)False

Question 9

In a double-sampling plan, a second sample is taken if the results of the first sample are inconclusive.

Accepted Answer

A) True 
 B)False

Question 10

The purpose of acceptance sampling is to:

Accepted Answer

A)  estimate process quality. 
B)  estimate lot quality. 
C)  detect and eliminate defectives. 
D)  decide if a lot meets predetermined standards. 
E)  accept samples of products. 
A)  estimate process quality. 
B)  estimate lot quality. 
C)  detect and eliminate defectives. 
D)  decide if a lot meets predetermined standards. 
E)  accept samples of products.

Question 11

Suppose that only two incoming fraction defective levels, 2 percent and 6 percent, are possible. The 2 percent incoming fraction defective level is twice as likely as the 6 percent. At a 2 percent incoming fraction defective, there's an 80 percent chance that a lot will be accepted. At 6 percent incoming fraction defective, there's a 20 percent chance that a lot will be accepted. Lots that are not accepted are subject to 100 percent sorting. What is average outgoing quality (approximately)?

Accepted Answer

A)  1.60 percent 
B)  1.47 percent 
C)  1.20 percent 
D)  .73 percent 
E)  .80 percent 
A)  1.60 percent 
B)  1.47 percent 
C)  1.20 percent 
D)  .73 percent 
E)  .80 percent
