$(8)$ Suppose you go to this thing called Google and figure out how to calculate an exponential smoothing with trend adjustment forecast. You run the numbers and

the MAD is $65$ and the average bias is $-17\mathrm{.}3.$ What logic below would be reasonable for implementing the exponential smoothing with trend adjustment forecast or the regression forecast that we already calculated?

A$.$ All of the above are reasonable approaches to forecasting demand for this product

B$.$ Use multiple forecasts weighted by accuracy

C$.$ Implement exponential smoothing with trend adjustment because it is more accurate

and you can adjust for bias

D$.$ Implement the regression forecast because the accuracy is close to the exponential

smoothing with trend adjustment and shows signs of no bias
