Remember, the employees always use the control limits they are given by management. Use the control limits from above. Create a Xbar chart and a R chart graph for the data points below by inserting rows and place the charts below the three data points shown State your conclusions for each of the sample. 12 13 14 XI 18.20 18.20 18.20 18.30 18.30 18.20 18.40 18.50 18.90 18.10. 18.20 18,60 18.00 18.10 19.30 222222 X2 X3 X4 X5 Xb ar CLA UCLA LCLX CLR UCLR LCLR R= ~*~** 2
