Variables with t and Chi-sq distributions

  1. Jul 15, 2009 #1

    I wish to know if there are any naturally occurring variables that have a t-distribution or chi-distribution.

    I know that test statistics such as the mean or the sum of a sample has a t-distribution, where as the variance of a sample takes the chi-distribution. What I am trying to understand is why these statistics take a particular distribution.
