Suppose ACT Reading scores are normally distributed with a mean of 21.321.3 and a standard deviation of 66. A university plans to award scholarships to students whose scores are in the top 4%4%. What is the minimum score required for the scholarship? Round your answer to the nearest tenth, if necessary.

I think this is intended to be a mean of 21.3

a standard deviation of 6

and the top 4%

(I've noticed in the past that numbers are sometimes doubled up here - no idea why!)

 

The top 4% occur above about 1.75 standard deviations, so the minimum score is 

21.3 + 1.75*6
