If it can be assumed that the binomial parameter θassumes a value close to zero, upper confidence limits ofthe form θ < C are often useful. For a random sample ofsize n, the one-sided intervalθ <12nχ2α,2(x+1) has a confidence level closely approximating (1 − α) 100%. Use this formula to find a 99% upper confi-dence limit for the proportion of defectives produced by a process if a sample of 200 units contains threedefectives.
