Adistribution is not symmetrical if the tails on both ends of the density curve that represents it are close to identical.
a. true
b. false

Option B. FALSE.

These tricky kind of questions are helpless.

You can say it is FALSE, because the two ends of the density curve that represents it are IDENTICAL.

Close to identical is not enough, but you can imagine that some times close to identical means that you see them identical and cannot tell if they really are. That is why I think this kind of questions does not help to clarify the concepts.
