Using the notation of the text, letting β0 = 3.0 and β1=2.0 in a regression model implies that: correct answers Y is expected to increase by 2.0 units if X increases by 1 unit 
 
If R^2 = 0.8, then correct answers SSR/TSS = 0.2 
 
In a linear regression the one regressor, the standard error of the regression (SER) is defined as correct answers sqrt(SSR/(n-2)) 
 
In the simple linear regression model, the regression slope correct answers indicates by how many units Y increases, given a one unit...
