Last steps

Compute the average

2015	2016	2017	2018	2019	Sum	Average
-42	-44	-46	-47	-41	-220.0	-44.0

Compute the Upper Control Limit

Simply compute the standard deviation and multiply by 3 and add to the average: -38.0

Compute the Lower Control Limit

Simply compute the standard deviation and multiply by 3 and subtract from the average: -50.0

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