Last steps

Compute the average

2015	2016	2017	2018	2019	Sum	Average
-43	-32	-36	-29	-36	-176.0	-35.2

Compute the Upper Control Limit

Simply compute the standard deviation and multiply by 3 and add to the average: -20.2

Compute the Lower Control Limit

Simply compute the standard deviation and multiply by 3 and subtract from the average: -50.2

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