The estimated regression equation for a model involving two independent variables and 15 observations is:

yhat = 30.13 - 0.58X1 + 2.54X2 

Other statistics produced for analysis include: SSR = 7120.3, SST = 7835.5, Sb1 = 0.08, Sb2 = 0.32.

1. Interpret b1 and b2 in this estimated regression equation
2. Predict y when X1 = 50 and X2 = 120.
3. Compute R and Ra.
4. Comment about 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 for the significance of β1. Use a level of significance of 0.05.
8. Perform a t test for the significance of β2. Use a level of significance of 0.05.
