The specifications for a plastic liner for a concrete highway project calls for

thickness of $3\mathrm{.}0mm+-0\mathrm{.}08mm.$ The standard deviation of the process is

estimated to be $0\mathrm{.}02mm.$

The upper specification limit for this product $=3\mathrm{.}08mm($round your

response to three decimal places$).$

The lower specification limit for this product $=,mm($round your

response to three decimal places$).$

The process is known to operate at a mean thickness of $3\mathrm{.}0mm.$ The

process capability index $(C_{pk})=,($round your response to three

decimal places$).$
