As part of an effort to induce the public to conserve energy, a researcher wanted to analyze the factors that determine home heating costs. In a city known for its long, cold winters the researcher took a random sample of 35 houses and collected data on the following variables: cost of heating during the month of January, house size in hundreds of square feet, number of windows, and number of occupants per house. A multiple regression model for the cost of heating was estimated with the Excel output shown below: SUMMARY OUTPUT Regression Statistics Multiple R R Square Adjusted R Square Standard Error Observations ANOVA Regression Residual Total Intercept Size Windows Occupants 0.554 0.511 34.898 35 Df 3 31 34 Coefficients 11.088 5.632 3.179 15.431 SS 46919 37754 84673 Standard Error 4.532 1.489 1.966 6.850 MS 15639.7 1217.9 t Stat 2.45 3.78 1.62 2.25 F 12.84 P-value 0.0202 0.0006 0.1154 0.0316 Significance F 0.000
