Fitting a straight line to a set of data yields the following prediction line. Complete (a) through (c) below. ₁ = 8+ 9x₁ a. Interpret the meaning of the Y-intercept, bo- Choose the correct answer below. A. The Y-intercept, bo = 8. implies that the average value of Y is 8. O B. The Y-intercept, bo = 9. implies that when the value of X is 0, the mean value of Y is 9. O C. The Y-intercept, bo = 8. implies that for each increase of 1 unit in X, the value of Y is expected to increase by 8 units. D. The Y-intercept, bo = 8. implies that when the value of X is 0, the mean value of Y is 8. b. Interpret the meaning of the slope, b₁. Choose the correct answer below. A. The slope, b₁ =9, implies that for each increase of 1 unit in X, the value of Y is expected to increase by 9 units. B. The slope, b₁ = 9, implies that the average value of Y is 9. O C. The slope, b₁ = 8, implies that for each increase of 1 unit in X, the value of Y is expected to increase by 8 units. O D. The slope, b₁ =9, implies that for each increase of 1 unit in X, the value of Y is expected to decrease by 9 units. c. Predict the mean value of Y for X = 5. (Simplify your answer.)
