X C 2 0 A researcher wants to mu the relationships between transportation price and several variables. distance of travel, speed ur transportation" and "seat of travel". 30 samples were selected: Coefficient Standard Error t Stat P-value Intercept 3.738 1.568 -2.239 0.028 Distance 1.084 0.428 12.287 4.2E-10 Speed 1.908 3.387 5.621 0.0008 Seat 6.065 3.821 6.841 5.2E-5 and here is the ANOVA table: df SS MS F Sig. F Regression 5342.8 9.21E-12 Residual Total 6832.5 Please type your answer by order (please keep 3 decimals)! 1. Type the results in the ANOVA Table: SSE, MSR, MSE, F. 2. Type the 90% confidence interval for the slope of Speed of transportation (Speed). 3. Suppose this study would like to use the Seat of travel (Seat) as the only independent variable in order to predict the transportation price and SSxx=67.5 SSxy=220.4 [x= 88.7 Ey=18546 Type the regression equation and interpret the regression line. 4. Using the regression line found in question 3 , type the result of the estimated transportation price if the seat of travel is 2
