assuming that better than average means more than 50% replies are:
23 humans; 31 martians.
martian year has 669.59 days (martian days!)
reply is always 31 martians, even if martian have a calendar made by 669 days or 670 (in fact we should assume they have a calendar with some kind of correction, like our 29th february, if they had a gregorian calendar, but maybe they neither have a pope);

You should check the other topics before you post an answer to a Grey Labyrinth puzzle. This has already been discussed in the thread titled "Happy Birthday," which I started and where I was, unfortunately, very wrong. Poor, stupid Murray.
