Use data file "Ch11_SatScore.xlsx". Based on the regression output in Question 3, what is the value of R-sq and what does it tell you about the regression?

I. R-sq = 2.47%, which implies about 2.47% of the overall variation in the response can be explained by the regression.

II. R-sq = 2.47%, which implies about 2.47% of the data fall on the regression line.

III. R-sq = 2.47%, which implies a strong positive relationship between the response and the predictor.

IV. None of the above.
