More generally, the formula for the 95% confidence interval on the mean is: Lower limit = M - (tCL)(sM) Upper limit = M + (tCL)(sM) where M is the sample mean, tCL is the t for the confidence level desired (0.95 in the above example), and sM is the estimated standard error of the mean.
lower specification limit. The lowest level of process performance or product quality that is within the acceptable range defined by customer standards and measurements of defects in the process or product itself. Control charts for process improvement approaches such as Six Sigma typically include a lower specification limit, and may include an upper specification limit as well.
