Question

28. The ANOVA table below was created for a regression model with two explanatory variables. The model is attempting to use sales and assets to explain profits Source df SS MS Regression xx 6.803.40 Residual xX Xx 0.125 Total 14 8.30 What is the value of SSE? a. 1.38 b. 1.50 c. 1.63 d. 1.75 29. Refer to the ANOVA table given in the previous problem. What is the overall F statistic and the null hypothesis it is testing? a. 4.53, Ho : A = 0 b, 4.53, Ho : A=A=0 c. 27.2, Ho : 1=0 d. 27.2, H0 : 1 = 2 = 0 30. Refer to the ANOVA table used for the previous two problems. How much of the total variation in profit can be explained by the relationship with sales and assets? a. 18.1% b. 22.1% c. 81.8% d. 85.7%

Explanation / Answer

28. SSE = SST - SSR = 8.30 - 6.80 = 1.50

Option B is correct.

29. F = 3.40/0.125 = 27.2

Hence,

Option D is correct.

30. Total variation explained = SSR / SST = 6.80 / 8.30 = 81.8%

Option C is correct.
