Consider the following computer output from a multiple regression analysis relating the cost of car insurance to the variables: number of car accidents, driver's credit score, and safety rating of the car. Intercept Car Accidents (In last 3 years) Credit Score Safety Rating Answer Coefficients Standard Error 1071 192.78 - 117.81 -250.96 Does the sign of the coefficient for the variable safety rating make sense? Coefficients 109.78 20.34 12.34 24.95 t Stat 9.756 9.478: P-value 0.0000 0.0000 -9.547 0.0000 - 10.059 0.0000 O Yes, because it is expected that as the safety rating increases then the cost should decrease. O No, because it is expected that as the safety rating increases then the cost should also increase. O No, because it is expected that as the safety rating increases then the cost should decrease. O Yes, because it is expected that as the safety rating increases then the cost should also increase. Tables Keypad Keyboard Shortcuts
