$4\mathrm{.}13$ The data below are the thicknesses of rubber sheets measured in millimeters by a thickness gage. Two measurements have been taken of each specimen by each of the two operators. The specifications are at $0\mathrm{.}50$ and $1\mathrm{.}00$ mm$.$

Calculate the reproducibility and repeatability errors $($standard deviations$),$ and separate the gage variability and part variability.

Verify the adequacy of the gage in resolution and precision.
