The specification for a plastic liner for concrete highway projects calls for a thickness of $6\mathrm{.}0$ mm$\backslash$pm $0\mathrm{.}1$ mm$.$ The standard deviation of the process is estimated to be $0\mathrm{.}02$ mm$,$ and the process is known to operate at a mean thickness

of $6\mathrm{.}03$ mm$.$ What are the Cp$,$ Cpk indices for this process?
