1. The coefficient of determination (R 2 ) for the regression of the full model is 0.596504894 . 2. The proportion of variation in the rent explained by its linear regression on the explanatory variables is 0.575193533 when we adjust for the degrees of freedom. 3. In order to explain the explanatory power of the full model the appropriate hypothesis test is the (a) Overall F-test 4. The degrees of freedom associated with the test statistic in part 3 is (are) (d) 15 and 284 . 5. The value of the test statistic in part 3 is 27.98999498 corresponding p-value given by 2.372E-47 = 2.372e-47 . 6. At 5% level, based on the results of the test discussed in parts 3. to 5. we can conclude that the model estimated for explaining rent (a) has sufficient explanatory power, . 7. At 5% level, based on the full regression model, the appropriate test for evaluating the positive effect of the average size of bedrooms on rent of an apartment is a (an) (b) Individual t-test . 8. The degrees of freedom associated with the test statistic in part 7 is (b) 284 . 9. In the full model, the value of the commonly used test statistic and the p-value for testing whether the average size of a bedroom has any impact on the rent of the apartment are 7.721646456 and 1.9754E-13 = 1.9754e-13 , respectively.

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
