Hello, thank you for taking the time to post your question!

The list here has 36 values, so what we are looking for is the 33^rd largest value to mostly closely approximate the 90^th percentile.

Hopefully that gets you moving in the right direction! Feel free to reach out if you have any questions beyond that :)
