Data is collected from two processes each on n$=15$ samples and the reported values are as below:

$=9\mathrm{.}8$ and $=0\mathrm{.}2$

$=10\mathrm{.}5$ and $=0\mathrm{.}1$

If the specification limits are $10\backslash$pm $1$

$(1)$ What is Cpk for these two processes? What are the nonconforming rates in ppm$?$

$(2)$ Based on the nonconforming rates you found in part $(1),$ which process would you suggest?Data is collected from two processes each on n$=15$ samples and the reported values are as below:
