Answer #1

The multiple correlation coefficient is 0.92187417. This indicates that the correlation among the independent and dependent variables is positive. This statistic, which ranges from -1 to +1, does not indicate statistical significance of this correlation. 2. The coefficient of determination, R2 , is 84.99%. This means that close to 85% of the variation in the dependent variable (home prices) is explained by the independent variables. 3. The adjusted R-square, a measure of explanatory power, is 0.82795539. This statistic is not generally interpreted because it is neither a percentage (like the R2 ), nor a test of significance (such as the Fstatistic). 4. The standard error of the regression is $419,334, which is an estimate of the variation of the observed home prices, in dollar terms, about the regression
