Please compute all forecasts, and forecast errors. Please be sure to show your work for at least one period for each forecast and forecast error. (Only numbers will result in a ZERO on this problem). [Note the X and Y bar, and the slope are specified below]. Once All forecasts are specified below, please circle the best forecast in an alternate color, and comment on why this is the best forecast. Compute the forecast for the 11 period for the forecast models where this is possible.
