Question

Which of the following statements are correct? A. The statement that the random variable X is normally distributed with parameters is often abbreviated . B. If the random variable X is normally distributed with parameters , then . C. The graph of any 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. D. If the random variable X is normally distributed with parameters , then a large implies that a value of X far from may well be observed, whereas such a value is quite unlikely when is small. E. All of the above statements are correct

Answer 1

A. The statement that the random variable X is normally distributed with parameters is often abbreviated.

Explanation:

The X is normally distributed with parameters u and is often distributed as X ≈N (u 2 ). The correct answer is a. The statement that the random variable is normally distributed.
