done

Explanation:

In a right - skewed distribution, the tail on the right side is longer, pulling the mean in that direction. So the mean is greater than the median. In a left - skewed distribution, the tail on the left side is longer, pulling the mean down, making the mean less than the median. Without knowing if the given skewed graph is left - or right - skewed, we assume the common case of right - skewness (since it's more common in real - world data). In right - skewed data, the mean is greater than the median.

Answer:

The mean is greater than the median.
