Suppose the polymer$-$coating machine currently provides the following results:

VARIABLE

PROCESS MEAN

PROCESS STANDARD DEVIATION

Temperature

$165$ degrees

$2\mathrm{.}55$ degrees

Thickness

$4$ microns

$0\mathrm{.}42$ micron$$

Calculate the process capability ratio $($Cp$)$ for both the temperature and thickness variables. Is the polymer$-$coating process able to meet the engineering standards $99\mathrm{.}7\%$ of the time? Explain.
