Question 1 4 pts Consider the following two models, where x1 and 2 are quantitative: Model A: E(y) Bo + B121 + B2X2 + B3 a + Braz Model B: E(y) Bo + B12 + B2x2 Suppose that we have conducted a subset/partial F-test and found the p-value to be 2%. What can be said about the importance of curvature based on this result? We have insufficient evidence (at alpha equals 5%) of curvature for neither of our (two) independent variables We have insufficient evidence (at alpha equals 5%) of curvature for at least one of our two) independent variables o We have sufficient evidence (at alpha equals 5%) of curvature for neither of our two) independent variables We have sufficient evidence (at alpha equals 5%) of curvature for both of our two) independent variables We have sufficient evidence (at alpha equals 5%) of curvature for at least one of our (two) independent variables Question 2 4p
