Which of the following is true regarding the normal distribution?
A) Mean, median and mode are all equal
B) It has two modes
C) It is asymmetrical
D) The points of the curve meet the X-axis at z = -3 and z = 3

Question

Quizplus · Accepted Answer

The normal distribution is symmetrical and the mean, median, and mode all coincide at the center of the distribution. Therefore, option A is true. Option B is false because the normal distribution has only one mode. Option C is false because the normal distribution is symmetrical. Option D is false because the points of the curve never meet the X-axis, since the distribution extends to infinity in both directions. Instead, the curve approaches the X-axis asymptotically but never touches it.
