As a quality engineer, you're about to explain to management that the process being checked is stable and the capability indices are Cp$=1\mathrm{.}5$ and Cpk$=0\mathrm{.}75,$ which of the following can be concluded from the information given. Check all the correct statements $($only $4$ are correct$)$:

A$.$

The process is capable and on target

B$.$

The specification tolerance $($USL$-$LSL$)$ is twice as large as the process spread of six standard deviations.

C$.$

If the specification tolerance is known, we can determine the standard deviation

D$.$

The process can be made capable if the average can be shifted to target

E$.$

The process is showing out of control conditions over time

F$.$

The process is producing units that are outside the specification limits

G$.$

The process is in control
