I think the Q3 should be 11.5, not 12 as indicated. There are 15 elements in the data set, so Q3 would be the average of elements #11 and #12, not elements #12 and #13 as indicated in the hints.

Also, in a previous problem, Q2 and Q3 were the same number, but it was not possible to make the box do that.
