In the TV show The Deadliest Warrior, a battle is simulated between two of history's most celebrated fighters. Experts demonstrate the use of weapons these individuals used during their time. Data was collected from these demonstrates as far as their lethality. The data was then uploaded to a computer simulation program where the individuals would fight. They determine the victor by running 1000 simulated battles so that an individual could not win from a "lucky blow". Assuming the combatants are equal for these simulated battles, what is the minimum number of victories required for one of the combatants to be declared superior at the 95% level
