Predicting college GPAAn admissions officer claims that at his college the regression equation y=0.5 + 7x approximates the relationship between y=college GPA and x=high school GPA, both measured on a four-point scale.
a. Sketch this equation between x=0 and 4, labeling the x and y axes. Is this equation realistic? Why or why not?
b. Suppose that actually y=0.5 +0.7x. Predict the GPA for two students having GPAs of 3.0 and 4.0. Interpret, and explain how the difference between these two predictions relates to the slope.
