In a simple linear regression, the following sample regression equation is obtained: Å· = 447 - 29x. a. Interpret the slope coefficient. As x increases by 1 unit, y is predicted to decrease by 29 units. b. Predict y if x equals -16.
Added by Tracy J.
Step 1
The slope coefficient is -29. This means that as x increases by 1 unit, y is predicted to decrease by 29 units. So the correct interpretation is: $\boxed{\text{As x increases by 1 unit, y is predicted to decrease by 29 units.}}$ b. To predict y when x equals Show more…

In the simple linear regression model, the regression slope: A) represents the elasticity of Y on X. B) indicates by how many percent Y increases, given a one percent increase in X. C) when multiplied with the explanatory variable will give you the predicted Y. D) indicates by how many units Y increases, given a one unit increase in X.

In the simple linear regression model, the regression slope (a) indicates by how many percent Y increases, given a one percent increase in X (b) when multiplied with the independent variable will give you the predicted Y (c) indicates by how many units Y increases, given a one unit increase in X (d) represents the elasticity of Y on X (e) none of the above

In the equation of a linear regression, Y = b1X + b0, if b1 = -1.6 which means a. For each unit increase in x, average of y will decrease by 1.6 b. For each unit increase in x, average of y will increase by 1.6 c. For each unit increase in x, y will decrease by 1.6. d. For each unit increase in x, y will increase by 1.6
