If a school had 1531 students, about how many would you expect to have an IQ greater than 145?

Step-by-step explanation:

Approximately 95% of the population has IQ scores between 70 and 130. Approximately 99.7% of the population has IQ scores between 55 and 145. Only approximately 0.3% of the population has IQ scores outside of this interval (less than 55 or higher than 145).
