Find the standard deviation, ơ, for the binomial distribution which has the stated values of n and p. Round your answer to thenearest hundredth.21)21) n= 503; p=0.7A) o = 10.28B) o= 13.55C) o = 14.40D) o=7.87

Given that n =503 p =0.7 q = 1- p q = 1 - 0.7 q = 0.3 it follow binomial distribution with parameter n and p The standard deviation of binomial distribution is given as σ = npqσ = 503×0.7×0.3σ =10.28 hence option A is correct
