The estimated regression equation for a model involving two independent variables and 65 observations is: yhat = 55.17+1.1X1 -0.153X2 

Other statistics produced for analysis include: SSR = 12370.8, SST = 35963.0, Sb1 = 0.33, Sb2 = 0.20.

  1. Interpret b1 and b2 in this estimated regression equation
  2. Predict y when X1 = 65 and X2 = 70.
  3. Compute R-square and Adjusted R-Square.
  4. Comment on the goodness of fit of the model.
