Fitting a straight line to a set of data yields the following prediction line. Complete (a) through (c) below. = 17 0.7X; ... a. Interpret the meaning of the Y-intercept, bo. Choose the correct answer below. A. The Y-intercept, bo = 17, implies that when the value of X is 0, the mean value of Y is 17. B. The Y-intercept, b = -0.7, implies that when the value of X is 0, the mean value of Y is - 0.7. C. The Y-intercept, bo = 17, implies that the average value of Y is 17. D. The Y-intercept, bo = 17, implies that for each increase of 1 unit in X, the value of Y is expected to increase by 17 units. b. Interpret the meaning of the slope, b. Choose the correct answer below. A. The slope, b = -0.7, implies that for each increase of 1 unit in X, the value of Y is estimated to decrease by 0.7 units. B. The slope, b = 17, implies that for each increase of 1 unit in X, the value of Y is expected to increase by 17 units. C. The slope, b = 0.7, implies that for each increase of 1 unit in X, the value of Y is expected to increase by 0.7 units. D. The slope, b = -0.7, implies that the average value of Y is -0.7. c. Predict the mean value of Y for X = 5. = (Type an integer or a decimal.)
