# Empirical distribution function for sample

I have a short question regarding empirical distribution function.

We have a sample of $(1, 2.1, 1.5, 3)$. What's the value of the empirical distribution function for this sample $F_{4}$ at $x=2$?

• The question asks what proportion of the sample has values less than or equal to $2.$ – whuber Jun 16 '18 at 14:57
