The Study

The Signficance Test:

P= The proportion of females in the morning crossfit classes vs males in the morning crossfit classes.

Ho: p=0.5

Ha: p=! 0.5

a: 0.05

  Two proportion Test:   

z= 13.70

P-value: 0.000

Conclusion: We fail 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.

P= The proportion of females in the afternoon crossfit classes vs males in the afternoon crossfit classes.

Ho: p=0.5

Ha: p=!0.5

a: 0.05

Two proportion Test:  

z= 2.04

P-value: 0.041

Conclusions: We 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.
