Use the following information from a multiple regression analysis to complete parts (a) through (c) below. n=20 b₁ = 10 b₂ = 35 S₁ = 6 = 8 Sp₂ Is there evidence that the variable X₂ contributes to a model already containing X₁? OA. No, since the null hypothesis is not rejected. O B. No, since the null hypothesis is rejected. OC. Yes, since the null hypothesis is rejected. O D. Yes, since the null hypothesis is not rejected. On the basis of these results, indicate the independent variables to include in this model. Choose the correct answer below. OA. Include both variables X₁ and X₂. OB. Include only the variable X₂. OC. Include neither variable X₁ nor X₂.
