Question 2. For the data below: a) Compute the exact values of the intercept and the slope from the regression equations. b) What are the forecasts obtained for years 11

through 14 from the regression equation obtained in part a? c) Assume that the forecast for year 10 is 430, and the observed demands for years 11through 14 are: What are the forecasts for years 11 through 14 using exponential smoothing method?(Suppose a =0.1)E = aD,,+(1-a)Ę, d) Using the forecasts obtained in parts b and c, compute MAD measure and determine which method provides a more accurate forecast for the given data.
