Rejectable quality level (RQL) is the ________ allowable percent defectives for the purpose of sampling inspection that the consumer finds definitely unacceptable.

To construct an operating characteristic curve, an agreement has to be reached between producer and consumer through which of the following points? 1. Maximum proportion of defectives that will make the lot definitely unacceptable 2. The producer is willing to accept that some of satisfying the quality level (AQL) will be rejected (α = 5%) 3. Maximum level of percentage defectives that will make the lot definitely unacceptable 4. The consumer is willing to take lots of quality level (LTPD) even though they are unacceptable (β = 10%)

1, 2 and 3 only

B

1, 2, 3 and 4

C

1, 2 and 4 only

D

2, 3 and 4 only
