Consider the following data for a dependent variable y and two independent variables, 1 and 2. x1 X2 Y 29 12 94 47 10 109 24 17 113 51 17 179 41 5 95 51 19 175 74 7 170 37 13 118 59 14 143 76 17 212 The estimated regression equation for these data is ŷ -15.59 +1.95x1 +4.67x2 Here SST 15,147.6, SSR = 14,085.2, Sb₁ = 0.2372, and Sb₂ = 0.8828. 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 B₁ significant? Use a = 0.05 (to 2 decimals). Use t table. tß₁ = The p-value is Select your answer - At a = 0.05, 31 Select your answer - significant. c. Is B₂ significant? Use a = 0.05 (to 2 decimals). Use t table. tß₂
