No answer provided yet.First, find the z-score for the 85th percentile using the percentile to z-score calculator (select 1-sided b/c we only want the 85th not the 15th percentile). You should get a z-score of 1.0369.

Next Setup an equation to find the raw score for the z-score of 1.0369.

(x-40)/7 = 1.0369

Solve for x:

x-40 = 7.2583

x = 47.2583

So one need a score slightly higher than a 47 to score in the 85th percentile.
