Compute the Upper Control Limit
Simply compute the standard deviation and multiply by 3 and add to the average: -23.8
Compute the Lower Control Limit
Simply compute the standard deviation and multiply by 3 and subtract from the average: -71.8
For the lines, you have the data necessary to plot the chart.
