28. What is the correct interpretation of the R-squared in Model 2 4) of the variation in household savings can be explained by household income, the household head, and the level of education of the household head b) 8% of the variation in the residuals of the model can be explained by household the household head, and the level of education of the household head 8% of the variation in household savings cannot be explained by the explanatory variables model 6e, household income, the age of the household head, and the level of education household head) d) 8% of the variation in the residuals of the model cannot be explained by the explanatory variables in the model (e., household income, the age of the household head, and the level of education of the household head) 29. Which of the two models (Model 1 vs Model 2) has a better f a) Model 2 because the R-squared in larger b) c) Both models have the same fit Model 1 because the adjusted R-squared is larger d) Model 2 because it has more variables to predict the outcome 30. Use the p-value approach and a significance level of 5% to test the null hypothesis that Model 2 is significant Ho: B₁ B₂=B₂ 0. What do you conclude? = a) We fail to reject the null hypothesis since the p-value of the test is 2. 80, and conclude that the model is significant. b) We fail to reject the null hypothesis since the p-value of the test is 0.044, and conclude that the model is significant. c) We reject the null hypothesis since the p-value of the test is 2. 80, and conclude that the model is not significant. d) We reject the null hypothesis since the p-value of the test is 0.044, and conclude that the model is significant.
