Quiz #6

Let’s say that after running a multivariate regression, you get this final table:

6.1 Which of the above (by name) is the least significant independent variable?

6.2 Similar to 6.1: Which of the above is the most significant independent variable?

6.3 Assume that the above table is in $; by how much does the average-priced home change in value if it adds two more bathrooms to its structure?

Now consider this second table from the same analysis:

6.4 As a percentage, how much of the variability in home prices can be attributed to

the variability of the above model’s independent variables’ values?

6.5 If we lost two degrees of freedom for the above analysis, then how many degrees of freedom will have been used in the analysis <HINT: Consider what the sample size must be.>

BONUSLAND [5 pts]: Reconsider the first table above; how much will the average priced home change in value if we add 2500 ft2 more land, on which we add 2200 ft2 of living space and in which we add two more bathrooms?
