Answer A, B and C

Check my work 2 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 Variable Coefficient Standard Error t Statistic Intercept 5. 6900 0 . 12792 44. 48 eBook Sale price -0. 0738 0. 0286 -2.58 Sub-Zero brand 1. 1370 0. 1498 7.59 References Total capacity (in cubic ft) 0. 07473 0 . 00474 15. 76 Two-door, freezer on bottom 0. 04278 0. 08903 0 . 48 Two-door, side freezer Base Two-door, freezer on top -0. 3046 0 . 03636 -8.38 One door with freezer -0. 7154 0 . 1319 -5.42 One door, no freezer -0. 9196 0. 1391 -6. 61 (a) Write the regression model, being careful to exclude the base indicator variable.
