An control chart with 3-sigma control limits and subgroup
Chapter 15, Problem 17E(choose chapter or problem)
An \(\bar{X}\) control chart with 3-sigma control limits and sub-group size \(\mathrm{n}=4\) has control limits
\(\mathrm{UCL}=48.75 \text { and } \mathrm{LCL}=40.55\).
(a) Estimate the process standard deviation.
(b) Does the response to part (a) depend on whether \(\bar{r} \text { or } \bar{s}\) was used to construct the \(\bar{X}\) control chart?
