a. Interpret the meaning of the Y-intercept, bo. Choose the correct answer below. O A. The Y-intercept, bo = 14, implies that the average value of Y is 14. O B. The Y-intercept, bo = - 0.5, implies that when the value of X is 0, the mean value of Y is - 0.5. OC. The Y-intercept, bo = 14, implies that when the value of X is 0, the mean value of Y is 14. O D. The Y-intercept, bo = 14, implies that for each increase of 1 unit in X, the value of Y is expected to increase by 14 units. b. Interpret the meaning of the slope, b, . Choose the correct answer below. O A. The slope, b, = - 0.5, implies that the average value of Y is -0.5. O B. The slope, b, =0.5, implies that for each increase of 1 unit in X, the value of Y is expected to increase by 0.5 units. OC. The slope, b, = 14, implies that for each increase of 1 unit in X, the value of Y is expected to increase by 14 units. O D. The slope, b, = - 0.5, implies that for each increase of 1 unit in X, the value of Y is estimated to decrease by 0.5 units. c. Predict the mean value of Y for X=4.
