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 was developed by the Bureau of Labor Statistics. t Statistic Vartable Intercept Sale price Coefficient 5.2700 Standard Error e.12679 41.56 -0.0741 e.0239 -3.10 Sub-Zero brand 1.2056 e.1387 8.69 Total capacity (in cubic ft) Two-door, freezer on bottom Two-door, side freezer Two-door, freezer on top One door with freezer One door, no freezer e.07588 e.00626 e.07222 12.12 e.e5354 0.74 Base -е. зез1 e.03846 -7.88 -e.7693 e.1337 -5.75 -0.8381 e.1529 -5.48 (0) Write the regression model, being careful to exclude the base indicator variable.
