Which of these statements is not true about the variance in a binomial distribution B(n, p)? __________

Question

A. For a fixed p, the variance increases as n increases.

B. For a fixed n, the variance is maximum when p = 0.5.
C. The variance depends only on n.
D. The variance is constant for a specific n and p.
E. None of these are true.

Answer 1

The variance of a binomial distribution B(n,p) is np(1-p).

So can you figure out which ones are false?
