The commercial division of a real estate firm is conducting a regression analysis of the relationship between x, annual gross rents (in thousands of dollars), and y, selling price (in thousands of dollars) for apartment buildings. Data were collected on several properties recently sold and the following computer output was obtained. The regression equation is Y = 20.0 + 7.23 X Predictor Coef SE Coef T Constant 20.000 3.2213 6.21 X 7.230 1.3625 5.29 Analysis of Variance SOURCE DF SS Regression 41,587.4 Residual Error Total 51,984.1 a. How many apartment buildings were in the sample? X b. Write the estimated regression equation (to 2 decimals if necessary). y = * + x x c. What is the value of sby (to 4 decimals)? d. Use the F statistic to test the significance of the relationship at a .05 level of significance. Compute the Ftest statistic (to 2 decimals). X What is the p-value? Use Table 1 of Appendix B. p-value is less than .01 What is your conclusion? Conclude that the selling price is related to annual gross rents. e. Predict the selling price of an apartment building with gross annual rents of $60,000 (to 1 decimal). thousands
