a$)$ A process has a C

p

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 $50\mathrm{.}01$ has a C

p

of $1\mathrm{.}2$ and a C

pk

of $1\mathrm{.}0.$

What is the estimated process average X from which these indexes are derived,

and which direction does it shift?

$(10\%)$
