Annual animal exhibition

You visit an annual animal exhibition and come across a unique competition.

It is a competition wherein an ox is selected and put on display. The people including animal experts place bets on the estimated weight of the ox. The best guess would win the prize. Approximately eight hundred people participate in the competition.

If you are provided all the responses and now asked to take a guess, what will be your strategy for best guess?
