Question 371805: Which of the following statements is true regarding the normal distribution?
a. Mean, median, mode are not necessarily equal
b. It is symmetrical
c. It can have more than a single peak
d. The points of the curve touch the X-axis at z=-3 and z=3
e. All are true for a normal distribution
For normal distribution, I know that mean=mode=median. So a is true.
B is also true as normal distribution is symmetrical.
I'm not sure about the rest.
Also, correct me if I am wrong.

You can put this solution on YOUR website!
mean=mode=median -----> a) is false

b) is true

c) is false

d) is false (distribution doesn't touch x axis)

e) false because a) c) d) are false
