[QUOTE="GiTS, post: 4091143, member: 33808"] [h2]Homework Statement [/h2] 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. [h2]Homework Equations[/h2] 99% has a z score of 2.576 Somehow I have to turn that into a number using standard deviation. [h2]The Attempt at a Solution[/h2] z=(x-m)/stdev x=(stdev*z)+mean is x the number I am looking for? Thanks all! [/QUOTE]
