O A. No, because there is a pattern, trend, or cycle that is obviously not random and there are eight or more
consecutive points all above or all below the centerline.
B. Yes, because all of the criteria are satisfied.
C. Yes, because none of the criteria are satisfied.
O D. No, because there is at least one point lying outside of the region between the upper and lower control limits.
c. Choose the correct answer below.
O A. The manufacturer should proceed as before, because the number of defects is increasing.
B. The manufacturer should review their production process and attempt to remedy the cause of increasing
variation in the proportions of defects.
OC. The manufacturer should review their production process and attempt to remedy the cause of increasing
proportions of defects.
