A process is performing at an average $($Xbar$)$ equal to $\mathrm{.}496$ and sigma$-$hat equal to $\mathrm{.}001.$ The engineering tolerance for the feature being produced is $\mathrm{.}500+/-\mathrm{.}004.$ Answer the following two questions:

a$)$Worth $2$ points: What is the Cpk $($in this case, Cpk $=$ Cpl since the process average is below Xbar$)$ equal to given that the process average $($Xbar$)$ and the lower specification limit $($LSL$)$ are the same value?

Cpk $=\_\_\_\_\_\_\_\_\_\_$

b$)$Worth $3$ points: What would be the expected percent rejection rate? Draw a diagram of this with a bell curve to illustrate visually what this would look like.

Percent Rejection Rate: $\_\_\_\_\_\_\_\_\_\_\_$
