1. Invection-molding process. Columns (3) through (6) below display the measures of diameters for 6 hourly samples of four parts each. (1) Sample Number (2) Date 10/10 1 2 3 4 5 6 (3) X 5.03 5.05 4.99 4.98 4.95 5.00 Measurements (cm) (4) (5) X2 X2 4.98 5.01 5.03 5.05 5.03 5.01 5.05 5.05 5.04 4.99 5.05 5.01 (6) X4 4.95 4.98 4.96 4.94 4.99 4.97 Calculate & and R for each sample. Then calculate and R. Draw a mean chart and a range chart. Is the process in control?
