I don't understand how to do this, can someone please help me?

To determine the number of deer in a game preserve, a conservationist catches 391 deer, tags them and lets them lose. Later 534 deer are caught; 178 of them are tagged. How many total deer are in the preserve?

  • algebra - ,

    The 534 that were caught represent 178/391 of the total deer population. Therefore the total population is about
    534*(391/178) = 1173

    However there will be a statistical sampling error of about 5% in that number.
