Question

Which of the following statements are correct? E. The statement that the random variable X is normally distributed with parameters mu and ^2 is often abbreviated X N(mu, ^2). F. If the random variable X is normally distributed with parameters mu and sigma^2, then E(X) = mu and V(X) = sigma^2. G. The graph normal probability density function is symmetric about the mean and bell-shaped, so the center of the bell (point of symmetry) is both the mean of the distribution and the median. H. If the random variable X is normally distributed with parameters mu and sigma^2, then a large sigma implies that a value of X far from mu may be observed, whereas such a value is quite unlikely when sigma is small. I. All of the above statements are correct

Explanation / Answer

All 4 statements (E,F,G,H) are correct.

So answer is "I"
