Calculating median in grouped data using ArcMap

I got stuck when calculating the median age in grouped data (age ranges) for each feature (each feature is a single administrative unit). I have about 18,000 features.

Field names indicate age ranges: 0-14, 15-64, 65-100. In the "median" field I would like to calculate the median age for each feature. I found a website https://atozmath.com/StatsG.aspx?q=1 where you can calculate such a median for a single feature, for example the first feature from the attribute table above.

The page easily calculated the median for the first feature in the image, and the page also wrote how it calculated it, but I don't know how to write a universal script for a "median" field to calculate the median for each feature.
