The estimated regression equation for a model involving two independent variables and 65 observations is

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. (16 points)

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.

5.    Compute MSR and MSE.

6.    Compute F and use it to test whether the overall model is significant using a p-value (α = 0.05).

7.    Perform a t test using the critical value approach for the significance of β1. Use a level of significance of 0.05.

8.    Perform a t test using the critical value approach for the significance of β2. Use a level of significance of 0.05.
