Question:

In Problem 14.5 on page 583, you used horsepower and weight to predict mileage (stored in Auto2010). Using the results from that problem,
a. Determine whether there is a significant relationship between mileage and the two independent variables (horsepower and weight) at the 0.05 level of significance.
b. Interpret the meaning of the p-value.
c. Compute the coefficient of multiple determination, r2, and interpret its meaning.
d. Compute the adjusted r2.
