If a seriesu1,u2,...u2n + 1constitute a random sample from a normally distributed population, they any linear function A = S12n + 1(arur) will also be normally distributed; moreover its mean will be zero if S(ar) = 0, and its variance will be equal to that of the original population if S (ar2) = 1. Any other liner function B = S12n + 1(brur) will be distributed independently of the first if S(arbr) = 0, and in this case the sum of the squares,x= A2+ B2, will be distributed so that the chance of exceeding any particular value ofxise-x/e, where c is the mean value of x, equal to twice the variance of the population sampled.
