Let's say I have two samples of results of two bernoulli experiments.

H_{0} : p_{1} = p_{2}

H_{1} : p_{1} \neq p_{2}

And I want to try to reject

H_{0}

at a confidence level.
I already know a proper way to solve this, but I was wondering, if I have a confidence interval for

p_{1}

and

p_{2}

, at the same level of significance. Can I just check if the intervals overlaps each other to test this?
