The International Olympic Committee states that the female participation in the 2004 Summer Olympic ...

Hypotheses: H0: p = 0.42

.  The female participation rate in the Olympics is 42%.

H_A: p > 0.42 .  The female participation rate in the Olympics is greater than 42%.

Model: Okay to use the Normal model because the sample is random, these 454 athletes are less than 10% of all athletes at exhibitions, and np=(454)(0.42) = 190.68 ≥ 10 and Use a N(0.42, 0.023) model, do a 1-proportion z-test.

Mechanics: n = 454, x = 202, = = 0.445
z = = 1.09
P = P( > 0.445) = P = 0.138

Conclusion: With a p-value (0.138) so large, I fail to reject the null hypothesis that the proportion of female athletes is 0.42. There is not enough evidence to suggest that the proportion of female athletes will increase.
