In a large population, very close to
25% of the observations will fall below the
25th percentile (Q1), and close to 75% fall below the 75th percentile (Q3). The
Web site of the Educational Testing Service reports that on the SAT Verbal
test, with a possible perfect score of 800, the 89th percentile of 1,475,623
scores nationwide is a score of 670.
What is the best estimate of exactly how many scores were below 670?
