Hi To All Covers,
I seem to be experiencing a brain cramp of sorts.....I have conducted eight separate observational studies of a process that is measured in a binary manner; a go or no-go outcome.
Using minitab, I have constructed a p - bar chart; sample sizes have varied from 35 to 121 pieces or units. The p-bar over the eight separate observational studies is 8%.
Question: What sample size do I need to "ensure" that all subsequent observational studies & sample sizes are correct; will be large enough to detect a defect if one is present.
Regards,
