process has an upper spec limit of $20\mathrm{.}6$ oz$,$ a lower spec limit of $19\mathrm{.}5$ oz$,$ a mean of $20$ oz$,$ and a standard deviation of $0\mathrm{.}1$ oz$.$ If the management want a process that produces no more than $3\mathrm{.}4$ defects per $1$ million outputs. Calculate Ck and then determine if the process is capable according to the management's standard.
