Fitting a straight line to a set of data yields the following prediction line. Complete? (a) through? (c) below.
Yi=10+2Xi
a. Interpret the meaning of the? Y-intercept, b0. Choose the correct answer below.
A. The? Y-intercept, b0=10?, implies that when the value of X is? 0, the mean value of Y is 10.
B. The? Y-intercept, b0=2?, implies that when the value of X is? 0, the mean value of Y is 2.
C. The? Y-intercept, b0=10?, implies that for each increase of 1 unit in? X, the value of Y is expected to increase by 10 units.
D. The? Y-intercept, b0=10?, implies that the average value of Y is 10.
b. Interpret the meaning of the? slope, b1. Choose the correct answer below.
A. The? slope, b1=2?, implies that for each increase of 1 unit in? X, the value of Y is expected to increase by 2 units.
B. The? slope, b1=2?, implies that the average value of Y is 2.
C. The? slope, b1=10?, implies that for each increase of 1 unit in? X, the value of Y is expected to increase by 10 units.
D. The? slope, b1=2?, implies that for each increase of 1 unit in? X, the value of Y is expected to decrease by 2 units.
c. Predict the mean value of Y for X=4.
