For the following data set: image text in transcribed

a. Construct the multiple regression equation

b. Predict the value of y when x1 = 10.1, x2 = 8.5, x3 = 26.2.

c. What percentage of the variation in y is explained by the model?

d. Is the model useful for prediction? Why or why not? Use the α = 0.05 level.

e. Test H0: β1 = 0 versus H1: β1 ≠ 0 at the α = 0.05 level. Can you reject H0? Repeat for β2 and β3.
