If you can please show your work and round the correct decimal asked I would be very grateful! Thankyou!

Here are the actual tabulated demands for an item for a nine-month period (January through September). Your supervisor wants to test two forecasting methods to see which method was better over this period. ACTUAL 124 136 MONTH January February March April May June July August September 154 172 164 182 144 134 142 a. Forecast April through September using a three-month moving average. (Round your answers to 2 decimal places.) Month Three-Month Moving Average April | May June July August September b. Use simple exponential smoothing with an alpha of 0.20 to estimate April through September, using the average of January through March as the initial forecast for April. (Round your answers to 2 decimal places.) Month Exponential Smoothing April | May June July August September C-1. Calculate MAD for each method. (Round your answers to 2 decimal places.) MAD Three-month moving average Exponential smoothing c-2. Use MAD to decide which method produced the better forecast over the six-month period. Exponential smoothing. O Three-month moving average
