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 α and β minimize MAD for this dataset.

α=0.2, β=0.8; α=0.4, β=0.2; α=0.9, β=0.7

First find the MAD for each pair of values, α, and β.
