Given the Upper Specification Limit of $8\mathrm{.}8,$ Lower Specification Limit of $8\mathrm{.}2,$ and the SD is $0\mathrm{.}389,$ average is $8\mathrm{.}411.$ now calculate Cp and Cpk $($see pp$.246-7$ of your textbook$).$ Now, explain if and why the process is capable or incapable. $($Tip: First you need to calculate and explain what Cp and Cpk are in this case, i$.$e$.$ the actual numbers. Then you need to explain what those numbers mean. See page $247).$
