Suppose that you are a manager for a factory that produces coats. You want to create a regression model with several variables to predict the price that a customer will be willing to pay for a coat. You examine the price the customers were willing to pay for your past 29 coat designs, along with the amount of material used (measured in yards), number of brands involved with the design/advertising, and the number of designs on the coat. The results of your multiple linear regression model are displayed below: Variable Coeff SE(Coeff) t-ratio P-value Intercept 86.19 53.21 Material used 38.51 21.67 (yards) Number of 61.49 21.19 Brands Number of 39.49 Designs 18.43 Using this information, what is the degree of freedom for the t-ratio of each predictor variable
