Looking for a type of self-test on ballpark estimates

A number of years ago (I'm going to say with 90% confidence it was between one and ten years ago) I came across a test that asked you to provide a range for a number of values that you could make a somewhat educated guess at but probably wouldn't know the answer to off the top of your head (so, maybe, the land area of Maui, or the number of words in A Tale of Two Cities
). The goal was not to pinpoint the values, but to provide a range that contained the correct answer with 90% certainty, so, the best score was 9 out of 10 questions correct. A score of 10/10 was as bad as 8/10 -- the aim was to get 9, so that your ranges weren't ridiculously broad.
The only specific question I remember from the test was the weight of an adult (African I think) elephant. I remember this one because I guessed a range that I thought was reasonable and maybe a bit broad (like say 2000-8000 pounds) and the correct answer was way more than that (I'm apparently not alone here
Any leads? It doesn't have to have the same questions if there are variations of this test around.
