# Assume a binomial probability distribution has p = 0.80 and n = 400.a) what is the mean and standard deviation

Assume a binomial probability distribution has p = 0.80 and n = 400.
a) what is the mean and standard deviation
b) is this situation one in which binomial probabilities can be approximated by the normal probability distribution? Explain.
c) what is the probability of 300 to 310 successes? Use the normal approximation of the binomial distribution to answer this question. (Round your answer to four decimal places.)
