Samples of male and female triathletes who competed in the 2006 Ironman Coeur d’Alene were taken. It was found that 38 out of 406 male triathletes were from outside the U.S. and that 34 out of 300 female triathletes were from outside the U.S. We would like to prove that there is a difference in the proportion of male and female triathletes at Ironman Coeur d’Alene who are from outside the U.S. The appropriate test yielded a P-value of 0.392.
