Question 2: Five samples with four observations each have been taken with mean and range of the actual measurements (in inches) shown in Table below: (15 point) Sample 1 2 3 4 5 Mean 12.5 12.4 12.24 11.9 12.08 Range 0.3 0.32 0.25 0.4 0.35 Construct a mean and range chart and indicate whether the process is in control? (Note: This specifically means you need to draw the mean and range charts and identify whether the process is in control) (Point scale: 4 points for LCL and UCL, 5 points for mean chart and 5 points range chart, 1 point to determine process is in control or not)
