Assume that you have a binomial experiment with p = 0.3 and a sample size of 100. The value of the variance is
A) 30
B) 33.33
C) 100
D) 210

Question

Quizplus · Accepted Answer

The variance of a binomial distribution is given by the formula Var(X) = np(1-p), where n is the sample size and p is the probability of success. Therefore, the variance in this case is Var(X) = 100(0.3)(1-0.3) = 21. Therefore, the best choice is D, which is the closest to 21 among the options provided.
