Consider the following data for a dependent variable y and two independent variables, ₁ and €2. The estimated regression equation for these data is ŷ 14.61 +1.90x1 +4.63x2 Here SST = 15,379.6, SSR 13,898.3, sb₁ = 0.2734, and sb₂ = 1.0892. a. Test for a significant relationship among 1, 2, and y. Use a = 0.05. F = (to 2 decimals) The p-value is -Select your answer At a = 0.05, the overall model is Select your answer b. Is ₁ significant? Use a = 0.05 (to 2 decimals). Use t table. t₁ = The p-value is Select your answer - At a = 0.05, B₁ - Select your answer ✓ significant. c. Is B₂ significant? Use a = 0.05 (to 2 decimals).
