Last steps

Compute the average

2015	2016	2017	2018	2019	Sum	Average
-34	-48	-50	-48	-48	-228.0	-45.6

Compute the Upper Control Limit

Simply compute the standard deviation and multiply by 3 and add to the average: -27.6

Compute the Lower Control Limit

Simply compute the standard deviation and multiply by 3 and subtract from the average: -63.6

For the lines, you have the data necessary to plot the chart.
