The following data provides the values of sample mean X and the range R for the samples of size 5 each. Calculate the values for central line and control limits for mean-chart and range chart and determine whether the process is in control. Sample No. : 1 4 7 8 9. 10 Mean (X) 11.2 11.8 10.8 11.6 11.0 9.6 10.4 9.6 10.6 : 10.0 Range (R) 7 4 8. 7 4 8 4 7 : 9 (Conversion factors for m = 5 are A2 = 0.577, D3 = 0 and D4 = 2.115).
