Question 755544: The weight of all football players in high school teams is normally distributed with a mean of 200 pounds and a standard deviation of 25 pounds.
A player’s weight is at the 90th percentile of weights. (90 percent players have weight less than this weight) What is the weight of this player in pounds?
a. 250
b. 232
c. 242
d. 268
e. None of the above answers is correct.
I thought you were suppose to use the formula: P/100 *n
But I don't know what "n" should be or if that's even the formula I'm suppose to be using.

-----
Find the z-value with a left tail of 90%
invNorm(0.9) = 1.2816
----
Find the corresponding wt. value using x = z*s + u
wt = 1.2816*25+200 = 232.04 lbs
