Do red uniform wearers tend to win more often than those wearing blue uniforms in Taekwondo
tl tl tl tl tl tl tl tl tl tl tl tl tl tl tl tl



matches where competitors are randomly assigned to wear either a red or blue uniform? In a sam
tl tl tl tl tl tl tl tl tl tl tl tl tl tl tl tl



ple of 80 Taekwondo matches, there were 45 matches where thered uniform wearer won.

1. What is the parameter of interest for this study?
tl tl tl tl tl tl tl tl




A. The long-run proportion of Taekwondo matches in which the red uniform wearerwins

A. Yes, since 45 is larger than 40. tl tl tl tl tl tl




B. Yes, since the height of the dotplot above 45 is smaller than the height of thedotplot a
