## Homework Statement

So the question is, given a set of random numbers, find the mean and the value that will be >= 99% of the occurances. So for a set of random numbers between say, 1-100, if the mean is 50, how do I find out what number will be >= 99% of all observations of the time.

Havent taken stats in a long time. No book provided.

## Homework Equations

99% has a z score of 2.576

Somehow I have to turn that into a number using standard deviation.

## The Attempt at a Solution

z=(x-m)/stdev

x=(stdev*z)+mean

is x the number I am looking for???

Thanks all!
