Fitting a straight line to a set of data yields the following prediction line. Complete (a) through (c) below. Y_i = 2 + 9X_i Interpret the meaning of the Y-intercept. B_0. Choose the correct answer below The Y-intercept. B_0 = 2, implies that for each increase of 1 unit in X, the value of Y is expected to increase by 2 units The Y-intercept. B_0 = 2, implies that when the value of X is 0. the mean value of Y is 2. The Y-intercept. B_0 = 9. implies that when the value of X is 0, the mean value of Y is 9 The Y-intercept. B_0 = 2, implies that the average value of Y is 2 Interpret the meaning of the slope, b_1. Choose the correct answer below. The slope, b_1 =9. implies that for each increase of 1 unit in X. the value of Y is expected to increase by 9 units. The slope, b_1 =9. implies that for each increase of 1 unit in X. the value of Y is expected to decrease by 9 units. The slope, b_1 =2, implies that for each increase of 1 unit in X. the value of Y is expected to increase by 2 units. The slope, b_1 =9. implies that the average value of Y is 9
