Suppose you are given the following R and X-bar charts associated with the weights of bulk-packaged foods (in ounces); the LCL, CL, and UCL are based on a large number of historical observations, and you plotted the most recent 6 points of data. What could you conclude? To be clear, points #1 and #2 on the range chart are both below the CL, and point 2 is slightly higher than point 1; point #5 on the X-bar chart is below the UCL (it may be hard to see depending on your device).
