Question

Based on the equation: Yhat = 2.306 + 3.7X1 -2.9X2, how would you interpret the slope for X2?

When X2 = 1, Yhat = -2.9, when controlling for X1.

For every -2.9 change in X2, Yhat increases by 3.7, when controlling for X1.

For every 1 unit increase in X2, Yhat increases by 2.306, when controlling for X1.

When X2 = 1, Yhat = 3.7, when controlling for X1.

For every 1 unit increase in X2, Yhat decreases by 2.306, when controlling for X1.

For every 1 unit increase in X2, Yhat decreases by 2.9, when controlling for X1.

When X2 = 1, Yhat = -2.9, when controlling for X1.

For every -2.9 change in X2, Yhat increases by 3.7, when controlling for X1.

For every 1 unit increase in X2, Yhat increases by 2.306, when controlling for X1.

When X2 = 1, Yhat = 3.7, when controlling for X1.

For every 1 unit increase in X2, Yhat decreases by 2.306, when controlling for X1.

For every 1 unit increase in X2, Yhat decreases by 2.9, when controlling for X1.

Slopes are defined as the change in the dependent variable (Y) for evry unit change in that independent variable.

Hence, for X2, it has slope -2.9, so

OPTION F: For every 1 unit increase in X2, Yhat decreases by 2.9, when controlling for X1. [ANSWER]
