Suppose that the SAT math scores follow the normal curve very well with mean 514 and standard deviation 117 (based on 1.7 million seniors who took the SAT at any time during their high school years through June 2012). Find, approximately, the score obtained by someone who ranked 10th percentile from the top on the SAT math test. How many percent of them scored above 650? Pick 100 person at random, what is the probability that exactly 15% of them scored above 650? (Use the normal approximation with continuity correction)
