In my company we use 99% reliability with 95% confidence for high risk (patient safety), 95% reliability with 95% confidence for medium risk (functional defects) and 90% reliability with 90% confidence for low risk (cosmetic defects).
I found some very useful Beta tables in a book called Reliability Statistics by Robert A. Dovich. These tables allow you to calculate the reliability of a process (at a given confidence level) if you know the number of samples taken and the number of failures.
While these tables are very useful, I would love to know the mathematical formula behind them. Does anyone know it?

James
