Question 418515
Suppose that an engineering school honors program will accept only high school seniors with a math SAT in the top 10%. 
What is the minimum SAT score in math for this program? 
(SAT): μ = 500 σ = 100
---
Find the z-score with a right tail of 10%:
invNorm(0.9) = 1.2816
---
Find the corresponding x-score using x = zs+u
---
x = 1.2816*100 + 500
---
x = 128.16+500
x = 628.16
