Emission probability failure
Emission probability failure
(OP)
Hi,
I am looking at the probability of emission failures during a European emissions test. could any one please explain the following text:
With a minimum sample size of 3, the sampling procedure is set so that the probability of a lot passing a test with 40 % of the production defective is 0,95 (producer's risk = 5 %) while the probability of a lot being accepted with 65 % of the production defective is 0,1 (consumer's risk = 10 %).
Thanks,
Derek

For 40 % defectve parts the probability that at least one is defective of a sample lot of 3 is
1-.6^3=.784, not .95
For 65% it is
1-.35^2=.957, not .90

1-.35^3, not 1-.35^2

Thanks for taking the time to explain this. I think I get the gist of what is required. Have a good 06 one and all
