In a simple linear regression the following sample regressio

In a simple linear regression, the following sample regression equation is obtained: y-hat = 403 - 29x. a. lnterpret the slope coefficient. As x increases by I unit, y is predicted to increase by 29 units. As x increases by I unit, y is predicted to decrease by 29 units. As x increases by I unit, y is predicted to decrease by 403 units. As x increases by I unit, y is predicted to increase by 403 units. b. Predict y if x equals -13. y- hat

Solution

a)As x increase by 1 unit, y is predicated to decrease by 29 units

b) y = 403 - 29(-13) = 780
