Process capability

The specifications for a manifold gasket that installs between two engine parts calls for a thick$-$

ness of $2\mathrm{.}515mm+-0\mathrm{.}035mm.$ In other words, the process target is $2\mathrm{.}515$ mm with a tolerance of

$0\mathrm{.}035$ mm $.$ The standard deviation of the process is estimated to be $0\mathrm{.}01$ mm $,$ and the process is

currently operating at a mean thickness of $2\mathrm{.}52$ mm $.$
