Question 8 of 16 Test: Test-3 Previous question Fitting a straight line to a set of data yields the following prediction line. Complete (a) through (c) below. Y, = 15 - 0.2X; a. Interpret the meaning of the Y-intercept, bo- Choose the correct answer below. O A. The Y-intercept, bo = 15, implies that for each increase of 1 unit in X, the value of Y is expected to increase by 15 units. O B. The Y-intercept, bo = 15, implies that the average value of Y is 15. O C. The Y-intercept, bo = 15, implies that when the value of X is 0, the mean value of Y is 15. D. The Y-intercept, bo = - 0.2, implies that when the value of X is 0, the mean value of Y is - 0.2. b. Interpret the meaning of the slope, b, . Choose the correct answer below. O A. The slope, b, = 0.2, implies that for each increase of 1 unit in X, the value of Y is expected to increase by 0.2 units. O B. The slope, b, = - 0.2, implies that for each increase of 1 unit in X, the value of Y is estimated to decrease by 0.2 units C. The slope, b, = - 0.2, implies that the average value of Y is - 0.2. O D. The slope, b, = 15, implies that for each increase of 1 unit in X, the value of Y is expected to increase by 15 units. c. Predict the mean value of Y for X = 5. Y, = (Type an integer or a decimal.)
