Question $2(15\%)$ a$)$ A process has a Cp of $1\mathrm{.}2$ and is centered on its nominal value. What proportion of the specification limits are used by this process$$s measurements? $(5\%)$ b$)$ A process with specification limits of $5\backslash$pm $0\mathrm{.}01$ has a Cp of $1\mathrm{.}2$ and a Cpk of $1\mathrm{.}0.$ What is the estimated process average X from which these indexes are derived, and which direction does it shift?
