Per the OC curves, how high a probability of accepting lots The way I read the curves, its about 99 percent.Am I right If not, what is the percentage of lots expected to be accepted Thanks.
![]() If there are zero defectives, then the chance of acceptance should be 100 If the lot has 100 defectives, then the probability would drop to 0 The rest would fall somewhere in between. Look at the Operating Characteristic (OC) curves and they will show the probability of acceptance with a given defective. Does that mean that accepting a lot with.40 will fall just under 95 percent (based on.16 being 95 percent) Perhaps my question should be: Customer doesnt want lots with AQL more than.40 and wants Z1.4 tables used. If I want to say we are 95 percent confident (or even 90) that the lot is equal to or no worse than.40 percent defective, what inspection level should I have used Thanks for help given so far. The point is that it is very difficult to be sure of very small defect rates like this. If possible, you should see about measuring a variable instead of a passfail text. Of course the sample size in this case exceeds the lot size, so there would be 100 inspection and (theoretically) all defectives would be removed.
