How do you calculate the P-Value I have done what was asked in the questions and it still has not come out correctly. Perhaps I am not placing the decimal correctly.
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.

(a)Write the regression model, being careful to exclude the base indicator variable.(Negative amounts should be indicated by a minus sign. Round your answers to 4 decimal places.)

(b)Find thep-value for each coefficient, using 302 degrees of freedom. Using an= .01, which predictor variable(s) are not significant predictors?(Leave no cells blank - be certain to enter "0" wherever required. Round your answers to 4 decimal places.)

(c)By how much does the natural log of refrigerator price decrease from atwo-door,side freezermodelto atwo-door,top freezer model?(Round your answer to 4 decimal places.)
The natural log of the price decreases by
(d)Which model demands a higher price: the side freezer or the one door with freezer model?
- The side freezer
- The one door
