Problem $2$j$)$ Studying Figure $2,$ is the machining process on Machine A in control? Why yes or why not?

Question $10$ options:

Officially, the process is in control because all measured dimensions are within specified limits$,$ USL and LSL $($within tolerance$)$

Officially, the process is out of control because one or more of the sample averages $($X$.$bar$)$ lie outside the control limits$,$ UCL and LCL$.$ This does not mean that the machine is not doing a good job. This situation can happen if the machine is too good for the job it is doing

It cannot be determined whether the process is in control
