If you are last to act, you can check
this page to see how well hands stack up against random hands. If you are last to act, you don't need to win even 50% of the time, since there will be some dead money in the pot.
If you only want to call as the favorite, call with any pair, any ace, any king, Q5o, Q3s, J8o, J5s, T8o, T7s, and 98s.
However, you should also consider what is likely to happen if the player who pushed isn't called. That player is likely to push again, and you might be in a good position to call next hand. I think this means you should give up some of the more marginal hands.
