A process has a specification of $6+-4$ and a standard deviation $()$ of $1\mathrm{.}5.$ What is

the Cp value for this process?

$C_p=\frac{\text{u}\text{p}\text{p}\text{e}\text{r}\text{s}\text{p}\text{e}\text{c}\text{i}\text{f}\text{i}\text{c}\text{a}\text{t}\text{i}\text{o}\text{n}limit-\text{l}\text{o}\text{w}\text{e}\text{r}\text{s}\text{p}\text{e}\text{c}\text{i}\text{f}\text{i}\text{c}\text{a}\text{t}\text{i}\text{o}\text{n}limit}{6}$

$1\mathrm{.}33$
