Studies on a machine that molds plastic water pipe indicate that when it is injecting $25mm$ diameter pipe, the process standard deviation is $0\mathrm{.}50mm.$ The $25mm$ pipe has a specification of $25mm$ plus or minus $1\mathrm{.}0mm.$ What is the process capability index $(Cp)?$

$0\mathrm{.}50$

$0\mathrm{.}67$

$1\mathrm{.}00$

$2\mathrm{.}00$
