Homework Help: Statistics

Posted by Anonymous on Tuesday, March 19, 2013 at 6:01pm.

How high must a student score to place in the top 10% of all students taking the SAT?
Scores on the SAT verbal test in recent years follow approximately the Normal with mean 504 and standard deviation 111.

This is what I did.
1-.10=.9
Then I entered the data in my calculator using InvNorm (.9, 504, 111)
= 646.25
Thus the high score would have to be 647.

Am I right or am I wrong? If I'm wrong can you please guide me to the right answer and where I went wrong?

Thank you :)
