The data in Table $9$E$\mathrm{.}3$ are temperature readings from a chemical process in $\backslash$deg C$,$ taken every two minutes. $($Read the observations down, from left.$)$ The target value for the mean is $\backslash$mu $\_0=950.$

Estimate the process standard deviation. $($Excel Sheet$4$ named as StDev$)$

Set up and apply a tabular CUSUM for this process, using standardized values h $=5$ and k $=1/2.$ Interpret this chart. Provides UCL and LCL$($Excel Sheet$1$ named as CUSUM$)$

Construct an EWMA chart using L$=2\mathrm{.}7$ and $\backslash$lambda $=0\mathrm{.}1.$ Given the individual UCL and LCL for each observation. $($Excel Sheet$2$ named as EWMA$)$

Provide a Moving Average chart with w$=5.$ Provides UCL and LCL for each observation. $($Excel Sheet $3$ named as MA$)$
