An electronics component has $LSL=4\mathrm{.}2V,$ USL $=4\mathrm{.}8V,$ mean $=4\mathrm{.}5V,$ and standard deviation $=0\mathrm{.}1V.$ What is the process capability status?

$Cp=1\mathrm{.}0,Cpk=1\mathrm{.}0$; Process is marginally capable

$Cp=1\mathrm{.}0,Cpk=0\mathrm{.}8$; Process is not capable

$Cp=0\mathrm{.}8,Cpk=0\mathrm{.}8$; Process is not capable
