FORECASTING

Question 1 The following model was proposed for testing whether there was a significant interaction between two predictor variables x1 and x2, and a signification quadratic term x7 y = Bo+ Pix1 + B2x2+ 83x1x2 + B4xz + c. When the full model was fit to data from records of 60 observations, it was found that SSE = 801.90. Then when the reduced model was fitted it was found that SSE = 810.85. Do the data provide sufficient evidence to support the reduced model instead of the full model? Use a = 0.05. Show all necessary calculations before explaining your
