Normal Approximation to the Binomial
Recall the binomial distribution where
n = number of trials
r = number of successes
p = Probability (success)
q = 1-p = Probability (failure)
Thm: If np>5, and nq>5, then the binomial distribution can be approximated b

Solution:
A matrix A is positive definite iff
If Ax = 0, then
x Ax 0
T
x Ax 0
T
for all
x Rn
and since A is positive definite, x = 0. Therefore
A must be nonsingular.
We have the following statements:
