A coin was tossed 1000 times in an experiment to decide whether it really had an equal chance of coming up heads or tails. The decision was made in advance to declare the coind NOT FAIR if the observed outcome of the experiment had less than a 5% chance of happening. Would the coin be declared not fair if fewer than 470 of the 1000 tosses came up heads?
