5.13 Not really. Not having the time order information will not affect the calculated control limits for R or Xbar or those that plot outside the control limits.

The pattern in (b) matches control charts (4). The pattern in (c) matches control charts (5). The pattern in (d) matches control charts (1). The pattern in (e) matches control charts (3). 6.4 Sample Sample Mean 25 23 21 19 17 15 13 11 9 7 5 3 1 0.0640 0.0635 0.0630 0.0625 0.0620 _ _ X=0.062952 UCL=0.063910 LCL=0.061994 1 6.4a xbar chart
