Reject the lot C. Accept the lot D. Draw the OC to evaluate the quality of the plan E. None of the above The chart shows the AOQ for a single sampling plan with n=19 and c=4. The Average Outgoing Quality Limit for this plan would be approximately: A. 0.006 B. 0.05 C. 0.07 D. 0.28 E. It cannot be determined with the information provided.

Explanation / Answer

Ans:

19)

The maximum ordinate on the AOQ curve represents the worst possible quality that results from the rectifying inspection program. It is called the average outgoing quality limit, (AOQL ).

Here,maximum value of ordinate on the AOQ curve is 0.05

So,AOQL=0.05

Option B is correct.

18)Accept the lot.(As,2/130=0.015<3)

Option C is correct.
