Unformatted text preview: to give me the sample size figures for the next 20 outcomes. Once I obtained those numbers I copy/pasted them onto the second worksheet along with the xbar bar, UCL and LCL from worksheet one. Now I needed to figure out the sample mean for each run by adding up the four sample sizes and dividing them by four. Once this was complete we could construct a control chart from the data we have calculated. In the control chart you could see the sample mean being depicted by the blue line, the xbarbar being depicted by the pink line, the UCL line being depicted by the yellow line and the LCL being depicted by the light blue line. From this chart we can observe that no sample mean exceeded the UCL or went below the LCL.
