$1)$ Using the Product Forecasting Information that has been provided from FY$2020$ through FY$2023$

$($four years$),$ calculate the measures of forecast accuracy $($MFE$,$ MAD, and MAPE$)$ for the Weighted

Moving Average $($MA$)$ and the Exponential Smoothing $($EXP$)$ approaches to forecasting.

a$)$ What are the values of MFE, MAD, and MAPE for each of these two approaches to

forecasting $($MA and EXP$)?$ Which of the approaches is more accurate?

b$)$ Do these forecasts seem sufficient for the purposes of decision making? Please support

your judgement with the available information $/$ KPI$$s we$$ve learned in this course
