It was recently reported that the average verbal SAT score this year was 423 points. It's also reported that 7% of those taking the test had scores of 600 or more, and 42% had scores of 400 or less. If the standard deviation of the SAT scores is 120, are the reported percentages consistent with what you'd expect if SAT scores follow a normal distribution? If the normal curve assumption is true, how likely is it that a random selection of one person who wrote the SAT that year would have a score of 650 or more?
