Last steps

Compute the average

2015	2016	2017	2018	2019	Sum	Average
-45	-39	-45	-33	-38	-200.0	-40.0

Compute the Upper Control Limit

Simply compute the standard deviation and multiply by 3 and add to the average: -25.0

Compute the Lower Control Limit

Simply compute the standard deviation and multiply by 3 and subtract from the average: -55.0

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