O A. No, because there is a pattern, trend, or cycle that is obviously not random. B. No, because there is at least one point lying outside of the region between the upper and lower control limits. C. Yes, because none of the criteria are satisfied. D. No, because there are eight consecutive points all above or all below the centerline.
