Which of the following correctly describes the normal probability distribution?
A) It is single-peaked above the random variable's mean, median, and mode, all of which are equal to one another.
B) It features tails extending indefinitely in both directions from the centre, approaching (but never touching) the horizontal axis, which implies a positive probability for finding values of the random variable anywhere between minus infinity and plus infinity.
C) Both a and b

Question

Quizplus · Accepted Answer

The normal probability distribution is symmetric and bell-shaped, with its peak at the mean, median, and mode, which are all equal. Its tails extend indefinitely, approaching the horizontal axis, indicating that it covers the entire range of real numbers.
