In case your info established isn't going to stick to a normal distribution, you might have to choose supplemental ways to properly estimate the control limits:
To discover the sample necessarily mean provided a assurance interval, discover the primary difference in the upper certain plus the mistake sure. In the event the error certain is mysterious, then ordinary the upper and lower bounds of the confidence interval to locate the sample suggest.
