Filling a straight line to a set of data yields the following prediction line. Complete (a) through (c) below. Y, =9+2X; a. Interpret the meaning of the Y-intercept, bo. Choose the correct answer below. O A. The Y-intercept, bo = 9. implies that when the value of X is 0, the mean value of Y is 9. O B. The Y-intercept, bo = 9. implies that the average value of Y is 9. O C. The Y-intercept, bo - 9, implies that for each increase of 1 unit in X, the value of Y is expected to increase by 9 units. O D. The Y-intercept, bo = 2, implies that when the value of X is 0, the mean value of Y is 2. b. Interpret the meaning of the slope. b, . Choose the correct answer below. O A. The slope, b, = 2, implies that for each increase of 1 unit in X, the value of Y is expected to increase by 2 units. O B. The slope, b, = 2, implies that for each increase of 1 unit in X, the value of Y is expected to decrease by 2 units. O C. The slope, b, = 9, implies that for each increase of 1 unit in X, the value of Y is expected to increase by 9 units. O D. The slope. b, = 2, implies that the average value of Y is 2. c. Predict the mean value of Y for X = 2 Y, =(Simplify your answer )
