• Explain how a confidence interval is related to a two-sided hypothesis test.

	Commonly-White Names	Commonly-Black Names	Total
Called back	[latex]246[/latex]	[latex]164[/latex]	[latex]410[/latex]
Not called back	[latex]2199[/latex]	[latex]2281[/latex]	[latex]4480[/latex]
Total	[latex]2445[/latex]	[latex]2445[/latex]	[latex]4890[/latex]

Let [latex]p_1[/latex]= true proportion of commonly-white named resumés that receive a callback.

Let [latex]p_2[/latex]= true proportion of commonly-black named resumés that receive a callback.

Let’s use technology to find the confidence interval for the data set.
