A gear has been designed to have a diameter of 3 inches. The standard deviation of the process is 0.3 inch. A control chart isshown. Each chart has horizontal lines drawn at the mean, µ, µ±20, and at u±30. Determine if the process shown is in controlor out of control. Explain.Is the process in control or out of control? Select all that applyA. In control, because none of the three warning signals detected a change.GearsB. Out of control, because there are nine consecutive points either above or below the mean.C. Out of control, because two out of three consecutive points lie more than two standarddeviations from the mean.D. Out of control, because a point lies more than three standard deviations beyond the mean.0 i 2 3 45 67 8 9 10 11Observation numberNext6:11 PMP Type here to searchOE 47°F Cloudy12/20/2021break3.4.JUKDlameter (Inches)4.
