Explanation:

Step1: Analyze data distribution

The data is right - skewed as there are a few high - value outliers (in the higher salary ranges with low frequencies).

Step2: Recall mean and median property

In a right - skewed distribution, the mean is pulled in the direction of the tail (higher values), while the median is the middle value and is less affected by outliers. So, the mean is greater than the median.

Answer:

The mean is greater than the median.
