Do red uniform wearers tend to win more often than those wearing blue uniforms in Taekwondo matches where competitors are randomly assigned to wear either
Do red uniform wearers tend to win more often than those wearing blue uniforms in Taekwondo matches where competitors are randomly assigned to wear either a red or blue uniform? In a sample of 80 Taekwondo matches, there were 45 matches where the red uniform wearer won. Given below is the simulated distribution of the number of "red wins" that could happen by chance alone in a sample of 80 matches. Based on this simulation, is our observed result statistically significant? 90 60 30 24 28 32 36 40 44 48 52 56 Number of heads O Yes, since 45 is larger than 40. Yes, since the height of the dotplot above 45 is smaller than the height of the dotplot above 40. O No, since 45 is a fairly typical outcome if the color of the winner's uniform was determined by chance alone. O No, since we could have observed a value greater than 45 just by random chance
