Example 2. Suppose the percentile rank of one student on the SAT is 90%, among the first-year students. Predict his percentile rank on first-year GPA. The scatter diagram is football-shaped. In particular, the SAT scores and GPAs follow the normal curve.

1. In example 2 (above) the regression method predicted that a student at the 90th percentile on the SAT would only be at the 69th percentile on first-year GPA. True or false, and explain: a student at the 69th percentile on first-year GPA should be at the 90th percentile on the SAT.
