A point which is outside of the lower control limit on an R-chart: A is an indication that no cause of variation is present. B. should be ignored because it indicates better performance. C. is impossible since the lower limit is always zero, D. should be investigated because an assignable cause of variation might be present, 12. Which of the following statements is True?
