Question 1

Acceptable quality level can be defined as the:

Accepted Answer

A)  quality level desired by the consumer.
B)  worst quality level the consumer can tolerate.
C)  probability of rejecting a good lot (i.e. ,when a lot is,in fact,acceptable to the consumer) .
D)  probability of accepting a bad lot (i.e. ,when a lot is,in fact,not acceptable to the consumer) .E) B) and C)
F) C) and D)

Question 2

The AOQ is often lower for a supplier with a high fraction defective than for a supplier with a comparatively lower fraction defective.Why wouldn't a supplier with a lower fraction defective always have a better AOQ?

Accepted Answer

Average outgoing quality is based on the...

Question 3

A manufacturer wants a sampling plan in which AQL = 0.02,LPTD = 0.12,α = 0.05,and β = 0.10.Which of the following values for n and c best satisfy these specifications? Table G.1 is appended to this exam.

Accepted Answer

A)  n = 54,c = 3
B)  n = 100,c = 2
C)  n = 200,c = 1
D)  n = 162,c = 0E) None of the above
F) B) and C)

Question 4

A double-sampling plan is usually less expensive than a single-sampling plan if the lot has a low number of defectives.

Accepted Answer

A) True 
 B)False

Question 5

A single-sampling plan by attributes is needed for a purchased component.Table G.1 is appended to this exam.
Sample size = 80
Acceptance number (c)= 1
Acceptance quality level (AQL)= 0.02
Lot tolerance proportion defective (LTPD)= 0.06
Given the preceding information,draw the OC curve for this plan.

Accepted Answer

The answer of A single-sampling plan by attributes is needed...

Question 6

Which one of the following alternatives will reduce the consumer's risk for a given AQL and LTPD?

Accepted Answer

A)  Reduce n and keep c constant.
B)  Increase n and keep c constant.
C)  Reduce n and increase c.
D)  Increase beta.E) B) and C)
F) B) and D)

Question 7

The distance between 1.0 and where the AQL intersects the OC curve is the value β (Beta).

Accepted Answer

A) True 
 B)False
