R2 Picture (3) Report the total variation, unexplained variation, and explained variation as shown on the output. (Round your answers to 4 decimal places.) Total variation Unexplained variation Explained variation (4) Calculate the F(model) statistic by using the explained variation, the unexplained variation, and other relevant quantities. (Round your answer to 3 decimal places.) F(model) (5) Use the F(model) statistic and the appropriate rejection point to test the significance of the linear regression model under consideration by setting α equal to .05. H0: β1 = β2 = β3 = 0 by setting α = .05. (6) Use the F(model) statistic and the appropriate rejection point to test the significance of the linear regression model under consideration by setting α equal to .01. H0: β1 = β2 = β3 = 0 by setting α = .01. (7) Find the p-value related to F(model) on the output. Using the p-value, test the significance of the linear regression model by setting α = .10, .05, .01, and .001. p-value = .000. H0 at α = .05, .01, and .001.
(1) Report SSE, s2, and s as shown on the output. (Round your answers to 4 decimal places.)
SSE= 1,953,635.6197 , s2=162,802.9683 , s =403.4885
(2) Report R2 and R⎯⎯⎯2 as shown on the output. (Round your answers to 4 decimal places.)
R2=.9958
(3) Report the total variation=, unexplained variation, and explained variation as shown on the output. (Round your answers to 4 decimal places.) Total variation=15 464,123,277.4907
Unexplained variation=1,953,635.6197
Explained variation =462,169,641.8709
(4) Calculate the F(model) statistic by using the explained variation, the unexplained variation, and other relevant quantities. (Round your answer to 3 decimal places.) F(model)
F=946.2760
(5) Use the F(model) statistic and the appropriate rejection point to test the significance of the linear regression model under consideration by setting α equal to .05. H0: β1 = β2 = β3 = 0 by setting α = .05.
rejection region=3.49
(6) Use the F(model) statistic and the appropriate rejection point to test the significance of the linear regression model under consideration by setting α equal to .01. H0: β1 = β2 = β3 = 0 by setting α = .01.
reject the H0 as the p-value of regression is less than alpha=0.01
or calcuateld F=946.276 is more than critical F(0.01)=5.9525
(7) Find the p-value related to F(model) on the output. Using the p-value, test the significance of the linear regression model by setting α = .10, .05, .01, and .001. p-value = .000. H0 at α = .05, .01, and .001
p-vaue=0.000
