For the Georgia Student Survey data file on the text CD, look at college GPA and high school GPA.
a. Identify the response and explanatory variables and construct a scatter-plot. What is the effect on this plot of several students having high school GPAs of exactly 4.0?
b. Find the sample prediction equation. Predict the college GPA for students having high school GPA of
(i) 3.0 and
(ii) 4.0. Explain how the slope relates to the answers.
