You have to construct SPC charts for weight and height. Construction, analysis and insights from SPC are the center piece of this case. Data are on Exhibit 3 and Exhibit 6. (In have shown you how to draw SPC using the example in the book. It is slightly different here, because they use different data to calculate the x double bar, R bar, upper and lower control limits for x bar charts and R chart. Otherwise the process is not very different.)

a. Use data on exhibit 3 to find x double bar, R bar, upper and lower control limits for x bar charts and R chart.

b. Use data on Exhibit 6 to make SPC charts (x bar and R), for weight and height.
