Agear has been designed to have a diameter of 3 inches. The standard deviation of the process is 0.3 inch. A control chart is shown. Each chart has horizontal lines drawn at the mean, p. ut 20, and at ut30. Determine if the process shown is in control or out of control. Explain Is the process in control or out of control? Select all that apply DA. In control, because none of the three warning signals detected a change. Gears OB. Out of control, because there are nine consecutive points either above or below the mean OC. Out of control, because two out of three consecutive points lie more than two standard deviations from the mean OD. Out of control, because a point bes more than three standard deviations beyond the mean Obnervation number

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 is shown. Each chart has horizontal lines drawn at the mean, µ, µ±20, and at u±30. Determine if the process shown is in control or out of control. Explain. Is the process in control or out of control? Select all that apply A. In control, because none of the three warning signals detected a change. Gears B. 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 standard deviations from the mean. D.
