Statistics Practice Question of the Week #17

This week’s practice problem is a Numeric Entry question, so instead of choosing an answer from a set of given possibilities, you’ll type in your answer before you submit.

Set A: {x, x, x, y, y, y, 3x+y, x–y }

If the median of set A is 10 and 0 < x < y, what is the range of set A?

We’ll be posting the answer tomorrow, good luck!

Update: Here’s the answer/explanation post!
