It is known that the SAT is normally distributed with a mean of 1000 and standard deviation of 200.
If any Ivy League school, such as Harvard, only wanted to accept students who had scores in the top 2.5%, what would be the minimum score Harvard would accept?

A. 1600

B. 1200

C. 1400

Answer 1

Mean + 2 sigma = 1000+400 =1400

Explanation:

Below of (Mean - 2 sigma) = 2.5%

Between (Mean - 2 sigma) and (Mean + 2 sigma) = 95%

Above of (Mean + 2 sigma) = 2.5%
