Fitting a straight line to a set of data yields the following prediction line. Complete (a) through (:3) below. vi=a+9xi e. interpret the meaning of the Yintercept. on. Choose the correct answer below. 0 A. The Y-intercept, b0 = 8, implies that the average value of Y is B. O B. The Yinteroept, co = 8. implies that for each increase of 1 unit In X, the value of Y is expected to increase by 8 units. 0 c. The Y-interoept, b0 = 9, implies that when the value of X is 0. the mean value of Y is 9. O D. The Y-intereept, b0 = 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. 0 A. The slope, b1 =9. implies that the average value of Y is 9. O B. 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. 0 c. 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. 0 D. The slope, b, = 8. implies that for each increase of 1 unit tn X. the value of Y Is expected to increase by 8 units. c. Determine the preredicted value of Y for x = 4. The predicted value Is '7i = D
