Question
A liquid-dispensing machine has been designed to fill bottles with 1.0 liter of liquid. The standard deviation of the process is 0.2 liter. A control chart is shown. The chart has horizontal lines drawn at the mean, p, at ut 2o, and at u±3o. Determine f the process shown is in control or out of control. Explain. Is the process in control or out of control? Ohoose the correct answer below. O A. Out of control, because there are nine consecutive points either above or below the mean. Liquid Dispenser O B. Out of control, because two out of three consecutive points lie more than two standard deviations from the mean. S 2- O C. In control, because none of the three warning signals detected a change. O D. Out of control, because a point lies more than three standard deviations from the mean. 0. 5 6 789 10 11 Observation number Liquid dispensed (in liters)
