Question

Fitting a straight line to a set of data yields the following prediction line. Complete (a) through (c) below. ?i = 11 - 0.7Xi a. Interpret the meaning of the Y-intercept, b0. Choose the correct answer below. A. The Y-intercept, b0 = - 0.7, implies that when the value of X is 0, the mean value of Y is - 0.7. B. The Y-intercept, b0 = 11, implies that the average value of Y is 11. C. The Y-intercept, b0 = 11, implies that for each increase of 1 unit in X, the value of Y is expected to increase by 11 units. D. The Y-intercept, b0 = 11, implies that when the value of X is 0, the mean value of Y is 11. b. Interpret the meaning of the slope, b1. Choose the correct answer below. A. The slope, b1 = - 0.7, implies that the average value of Y is - 0.7. B. The slope, b1 = - 0.7, implies that for each increase of 1 unit in X, the value of Y is estimated to decrease by 0.7 units. C. The slope, b1 = 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, b1 = 11, implies that for each increase of 1 unit in X, the value of Y is expected to increase by 11 units. c. Predict the mean value of Y for X = 5. ?i = (Type an integer or a decimal.)
