... That is, we estimated that the mean demand during lead time falls between 340.76 and 399.56, and this type of estimator is correct 95% of the time. That also means that 5% of the time the estimator will be incorrect. Incidentally, the media often refer to the 95% figure as “19 times out of 20,” whic ...
