Exit Submit Check my work Refrigerator prices are affected by characteristics such as whether or not the refrigerator is on sale, whether or not it is listed as a Sub- Zero brand, the number of doors (one door or two doors), and the placement of the freezer compartment (top, side, or bottom). The table below shows the regression output from a regression model using the natural log of price as the dependent variable. The model 2 was developed by the Bureau of Labor Statistics. points Standard Variable Coefficient Error t Statistic Intercept 5.3300 0.12060 44.20 E Sale price -0.0773 0.0279 -2.77 eBook Sub-Zero brand 1.1991 0.1394 8.60 Total capacity (in cubic feet) 0.06167 0.00630 9.79 Two-door, freezer on bottom 0.05059 0.08569 0.59 g Twodoor, side freezer Base _ Twodoor, freezer on top 0.3126 0.03677 8.50 \"'m One door with freezer 0.7994 0.1355 5.90 One door, no freezer 0.8608 0.1411 6.10 rii (a) Write the regression model, being careful to exclude the base indicator variable.
