Statistical process control charts (SPC charts) have a central line and upper and lower control limit lines. As discussed in the textbook, an SPC chart does not indicate the process monitored by the chart should be investigated when: O a) Erratic pattern in the plotted points O b) A large number of plotted points are close to the upper or lower control lines c) A single plotted point falls outside the control limits d) Process raw materials or operators change O e) A run of 5 plotted points above the central line
