First up thanks in advance to anyone who spends any time helping me out with this.

I have an attribute inspection on a small scale production line that has successfully detected 3 reject parts out of a total of 250 parts. From further testing i have been able to confirm that the remaining 247 parts were 'good' parts. Based on the above can I calculate the reliability/confidence for my inspection? In particular I am interested in what the likelihood of the inspection missing a defective part is (false negative).

I am using Minitab 16 if that is any help.

Thanks,

Dave
