I have a population of Z items, where X must pass and Y must fail. The thing is that the X that pass is not just a count (i.e. if 2 must pass, it has to be items A and B. It can't be C and D.) How do I figure out the sample size/what test should I use to test this? Also, how would I test it? Just have a sample size of items to fail? It needs to be risk-based, so ensuring all the failing items will fail with 90% confidence.
This may be super easy, but I can't seem to get my head around it having specific pass/fail items rather than just a 1 proportion test.
Thanks!!
