Do not include anything other than numbers in your responses. For example, do not include comma or dollar sign in your numbers. As a rule of thumb, keep 2 decimal places for larger numbers and 3 decimal places for smaller numbers less than 1. Consider the following data. We want to monitor the forecasts.

Period	Demand	Forecasts
1	52	--
2	62	58
3	59	62
4	53	66
5	58	68

We want to calculate the UCL and the LCL for the appropriate control chart to monitor the magnitute of errors.

Calculate the overall MSE to determine if the errors of the forecasts are in control. overall MSE:
UCL for the control chart?
LCL for the control chart?
Based on your control chart, are the forecasts in control? (Yes/No)
