An ancient Roman coin is found and a curious anthropologist wishes to determine if the coin is fair - Fair meaning that when flipped, it has a 50% chance of landing one way or the other. The anthropologist flips the coin 100 times and the coin comes up heads 72 times. Do you believe the coin is fair? What range of results would you expect if the coin was indeed fair?
