First find the MAD for each pair of values, a and ß. Coal Production (thousands of tons) 434,330 Year 1. 420.427 3. 439,044 4 477 200 504.182 526.949 7. 546,822 564.884 556,711 8 10 570,975 The total number of thousands of tons of coal produced per year over a 10-year period for a certain region is provided in the accompanying dataset. Use double exponential smoothing to determine which pairs of values for a and B minimize MAD for this dataset a=0.1, p=0.8, a = 0.4. B 0 2; a=0.9, = 0.6 Click the icon to view the coal production data
