For this question, please refer to the following control chart, which shows the results of the last 23 runs of a process. The process has been in operation for 500 runs, and each run takes 1 day.
Hmm, I'm not so sure. The data points seem to be within the control limits, so I think this is just normal variation in the process. Option C seems like the best choice here.
This is definitely a process shift. The data points are clearly outside the control limits, indicating a problem with the process. I'm confident that option A is the correct answer.
