## Question:

a. What is the degrees of freedom of regression?

b. What is the total degrees of freedom?

c. What is the SSR?

d. What is the MSR?

e. What is the MSE?

f. What is the F statistics?

g. Test the model significance at the level of significance of 0.05. State the hull hypothesis and alternate hypothesis. What is the critical F value used? Can you reject the null hypothesis?
