This is the desired

sum of n mutually stochastically independent normally distributed variables has a

normal distribution. The next theorem proves a similar

This is the desired

**result**. 1. 1 If, in Theorem 1, we set each k = 1, we see that thesum of n mutually stochastically independent normally distributed variables has a

normal distribution. The next theorem proves a similar

(b) If A is a square matrix and if L is an orthogonal matrix, use the

**result**of part (a)to show that tr (L'AL) = tra. (c) If A is a real symmetric idempotent matrix, use the
