Suppose we wish to build a multiple regression model to predict the cost of rent (dollars) in a city based on population (thousands of people), and income (thousands of dollars). Use the alpha level of 0.05.

Detroit, MI 650 713.777 29.447
Baton Rouge, LA 827 229.493 35.436

5. What are the values of the estimated slope for the variable “Population”? Interpret the value in terms of actual names of IVs and the DV.

6. Does Income significantly influence the Rent at the alpha level of 0.01? Make sure to show which values you use to make the decision.

7. Does Population significantly influence the Rent at the alpha level of 0.01? Make sure to show which values you use to make the decision.

When we estimate a linear multiple regression model (including a linear simple regression model), it appears that the calculation of the coefficient of determination, R2, for this model can be accomplished by using the squared sample correlation coefficient between the original values and the predicted values of the dependent variable of this model. Is this statement true? If yes, why? If not, why not? Please use either matrix algebra or algebra to support your reasoning.
