Conclusion

The first test was the proportion of females vs males that go to the morning crossit classes. I failed reject the  null hypothesis with the significance level of 0.05. There is not enough sufficient evidence to prove that the proportion of females in the morning crossfit classes vs males in the morning crossfit classes differ.

The second test was the proportion of females vs males that go to the afternoon crossfit classes. I  reject the null hypothesis at the significance level of 0.05. There is sufficient evidence to prove that the proportion of females in the afternoon classes vs males in the afternoon classes differ.
