Fitting a straight line to a set of data yields the following prediction line. Complete (a) through (c) below. Ý = 3 + 5X; a. Interpret the meaning of the Y-intercept, bo. Choose the correct answer below. A. The Y-intercept, bo = 5, implies that when the value of X is 0, the mean value of Y is 5. B. The Y-intercept, bo = 3, implies that when the value of X is 0, the mean value of Y is 3. C. The Y-intercept, bo = 3, implies that for each increase of 1 unit in X, the value of Y is expected to increase by 3 units. D. The Y-intercept, bo = 3, implies that the average value of Y is 3. b. Interpret the meaning of the slope, b,. Choose the correct answer below. A. The slope, b, = 5, implies that for each increase of 1 unit in X, the value of Y is expected to increase by 5 units. B. The slope, b, = 5, implies that for each increase of 1 unit in X, the value of Y is expected to decrease by 5 units. O C. The slope, b, = 5, implies that the average value of Y is 5. D. The slope, b, = 3, implies that for each increase of 1 unit in X, the value of Y is expected to increase by 3 units. c. Predict the mean value of Y for X = 4. Y = (Simplify your answer.)
