2.In the estimated regression equation Y = 0.78 - 1.5 X, which of the following is least accurate when interpreting the slope coefficient?
A) If the value of X is zero, the value of Y will be -1.5.
B) The dependent variable declines by -1.5 units if X increases by 1 unit.
C) The dependent variable increases by 1.5 units if X decreases by 1 unit.
D) -1.5 is the elasticity of Y with respect to X.
The correct answer was A)
The slope represents the change in the dependent variable for a one-unit change in the independent variable. If the value of X is zero, the value of Y will be equal to the intercept, in this case, 0.78.
