Dummy Variable Regression: Choose any metric variable as the
dependent variable (you can use the same one that you used in Part
A) and choose gender as an independent variable. Also choose one
more metric variable as an additional independent variable. Once
again, however, you must sort through the metric independent
variables until you find one that, along with gender, produces a
significant F-calc. Use alpha = .05 here as well. You
only need to report the model that produced...

2. Multiple coefficient of determination Macroeconomics is the study of the economy as a whole. A macroeconomic variable is one that measures a characteristic of the whole economy or one of its large-scale sectors. In forecasting the sales of a product, market researchers frequently use macroeconomic variables in addition to marketing mix variables (marketing mix variables include product, price, place [or distribution], and promotion). A market researcher is analyzing an existing multiple regression model that predicts sales for different brands...

For two valid regression models which have same dependent variable, if regression model A and regression model B have the followings, Regression A: Residual Standard error = 30.33, Multiple R squared = 0.764, Adjusted R squared = 0.698 Regression B: Residual Standard error = 40.53, Multiple R squared = 0.784, Adjusted R squared = 0.658 Then which one is the correct one? Choose all applied. a. Model A is better than B since Model A has smaller residual standard error...
