$...$Using your control charts, select the most correct answer from below.

Points $2,3,5$ and $11$ seem to be out of control because they exceed the LCL in the Xbar chart. With so many point breaking our control limits$,$ we should investigate further in the shop floor. This is cause

for great concern. The process is no longer in control and is performing erractically.

Glven that all points are within their respective limits$,$ this may suggest that the process has reached a change point whereby a new distribution characterizes its behavior. Additional investigation is

required. Management may need to reconstruct specification and control limits for this process.

Point $6$ exceeds the LCL in the Xbar chart, but the R chart is fine on that day. Therefore, no additional investigation is required at this time, but continued monitoring is advised. This is an indication that

the process may soon go out of control.

Point $6$ seems to be out of control because it exceeds the LCL in the Xbar chart. However, thereafter the process seemingly abides by its original control limits$.$ Anamolous activity may have occurred

on day $6.$ Further investigation is warranted on the shop floor.
