Actually the trend is to ensure 100% quality control
using automated inspection, but that's not what you
want to hear ;)

I think such a statement usually says "we have to take x samples
*out of our total of N objects* to be 95% sure that ...". Do you
have some N? I suppose it might be something like the estimated
