Help solving a-c please!

The accompanying data represent the yearly amount of solar power installed (in megawatts) in a particular area from 2000 through 2008. The trend forecasting equations below were found, where X is the number of years after 2000. Complete parts (a) through (d) below. Y = - 10.711 + 28.9000X; Y, = 22.70 + 0.259X; + 3.5801X?

Compute the MAD for each model. Linear Quadratic MAD 0 (Round to three decimal places as needed.) c. On the basis of (a) and (b) and the principle of parsimony, which forecasting model would you select? The model with the smallest values of Syx and MAD should be used, which is the model.
