At a state university, the first-year class numbers about 360. Until recently, few semifinalists (or finalists) in the National Merit Scholarship program attended. Now the state government has begun to offer its own scholarships to state residents who are National Merit semifinalists-but only if they attend a college in the state. In the first semester of the program, 40 National Merit Scholarship students enter the university. How did the distribution of SAT scores for the first-year class change? Which measure of central tendency changed most? Explain.
