Refer to the slot depth in Table 1 below. After the machine was repaired, a sample of three new ceramic parts had slot depths of 220, 223, and 215 at 3:00. (Thousandths of an inch) (a) Redraw the X-bar chart and include the additional meanX. Fill in the Sum(s) and X's and draw the graph showing the times from 6:30 until 3:00pm. (b) Does the new X fall within the control limits?
