Standard error for difference in proportions = 0.0150
Margin of error = 2.58*std error
= 0.0387

Since this confidence interval contains 0 for difference in proporiton we can say that H0 is true.
We are 99% confidence that for samples randomly drawn for large sizes, the males and females have approximately the same proportion.
