Answer: C) Mean and median are approximately equal
Step-by-step explanation:
If the mean and median are *exactly* equal, then the distribution is perfectly symmetric. That means the left side is a mirror copy of the right side.
For roughly symmetric distributions, the mean and median are approximately equal. We consider them close enough.
In cases when mean < median, then the distribution is left-skewed. The left side tail is pulled longer than the right side tail.
When mean > median, we have a right-skewed distribution. This is where the tail on the right is longer than the tail on the left.
