Question 1

The complete second-order model E(y) = β0 + β1x1 +  β2x2 + β3x1x2  + β4 +  β5 was fit to n = 25 data points. The printout is shown below.



a.Write the complete second-order model for the data.
b.Is there sufficient evidence to indicate that at least one of the parameters β1, β2, β3, β4, and β5
is nonzero? Test using
c.Test H0: β3 = 0 against Ha: β3 ≠ 0. Use α = .01.
d.Test H0: β4 = 0 against Ha: β4 ≠ 0. Use α = .01.


Question 2

True or False.

When testing the utility of the quadratic model the most important tests involve the null hypotheses H0:  β0 = 0 and H0:  β1 = 0.
