Residential real estate prices are thought to depend, in part, on property size and number of bedrooms. The house size X1 (in hundreds of square feet), number of bedrooms X2, and house price Y (in thousands of dollars) of a random sample of houses in a certain county were observed. The resulting data and some associated computer output were presented in Problem 10 of Chapter 8. Additional portions of the output ate shown here. Use all of the output to answer the following questions.
a. Perform the overall F test for the regression of Y on both independent variables. Interpret your result.
b. Perform variables-added-in-order tests for both independent variables, with X1 added first.
c. Perform variables-added-in-order tests for both independent variables, with X2 added first.
