Last steps

Compute the average

2015	2016	2017	2018	2019	Sum	Average
-64	-51	-60	-49	-51	-275.0	-55.0

Compute the Upper Control Limit

Simply compute the standard deviation and multiply by 3 and add to the average: -37.0

Compute the Lower Control Limit

Simply compute the standard deviation and multiply by 3 and subtract from the average: -73.0

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