QualiTech Inc. needs help in calculating its process capability indices. For a specific item, the lower and upper specification limits are $6\mathrm{.}1$ and $6\mathrm{.}6,$ respectively. The mean is $6\mathrm{.}3$ and the standard deviation is $0\mathrm{.}04.$

$1.$ What is the process capability index for the lower specification limit$?$ Show your work.

$6\mathrm{.}3-6\mathrm{.}1=0\mathrm{.}2$

$3$ x $0\mathrm{.}04=0\mathrm{.}12$

$0\mathrm{.}20/0\mathrm{.}12=1\mathrm{.}67$

$2.$ What is the Cpk statistic for the upper specification limit$?$ Show your work.
