SAT, take 2 Suppose we wanted to use SAT math scores to estimate verbal scores based on the information in Exercise 53.

 a) What is the correlation?

b) Write the equation of the line of regression predicting verbal scores from math scores.

c) In general, what would a positive residual mean in this context?

d) A person tells you her math score was 500. Predict her verbal score.

 e) Using that predicted verbal score and the equation you created in Exercise 53, predict her math score.

 f) Why doesn’t the result in part e come out to 500?
