If X is a random variable which is normally distributed with a mean of 100, then P(X<100)=P(X>100)

True or False?

If it is normally distributed, then the mean, median and mode have the same value.
The median is the point where half of the scores have a higher value and half have a lower value.

Do that help you answer your question?

Thanks for asking.

So, that would make the statement True.
