Question
Fitting a straight line to a set of data yields the following prediction line. Complete (a) through (c) below. Yi = 7 + 5x, a. Interpret the meaning of the Y-intercept, b. Choose the correct answer below. A. The Y-intercept, bo-7,implies that when the value of X is 0, the mean value of Y is7. O B. The Y-intercept, b0-7, implies that for each increase of 1 unit in X, the value of Y is expected to increase by 7 units. 0 C. The Y-intercept. bo" 5, implies that when the value of X is 0, the mean value of Y is 5. 0 D. The Y-intercept, bo = 7, implies that the average value of Y is 7. b. Interpret the meaning of the slope, b, Choose the correct answer below. 0 A. The slope, b1-7, implies that for each increase of 1 unit in x, the value of Y is expected to increase by 7 units. B. The slope, b1 5, implies that for each increase of 1 unit in X, the value of Y is expected to increase by 5 units. 0 C. The slope, b1-5, implies that the average value of Y is 5. 0 D. The slope, b1-5, implies that for each increase of 1 unit in X, the value of Y is expected to decrease by 5 units. c. Predict the mean value of Y for X 3. Yi = (Simplify your answer.)Explanation / Answer
from given regression equation predicted mean value of Y =7+5*3 =22
