Please type the assumptions required for a binomial normal approximation using inequalities and the following symbols (n,p,q) where n is the sample size, p is the probability parameter from the binomial experiment, and q=(1-p).

(write both answers together separated by a single space).

Solution

To perform the normal approximation to the binomial, then

np >= 5 AND nq >= 5 [ANSWER]
