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

and minimize MAD for this dataset.

=0.2,

=0.9;

=0.4,

=0.3;

=0.9,

=0.6

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

(Type integers or decimals rounded to two decimal places as needed.)

		MAD
0.2	0.9	nothing
0.4	0.3	nothing
