Statistical Inference for $p_1-p_2$

$n_1=$ $\hat{p}_1=$
$n_2=$ $\hat{p}_2=$

CI for $p_1 - p_2$:

$H_0:p_1-p_2$
$H_a:p_1-p_2$

Significance level: $\alpha =$

This applet computes performs inference for the difference between two population proportions, $p_1-p_2$.

Directions

To perform a hypothesis test for $p_1-p_2$, enter $H_0$ and $H_a$. Specify the null and alternative hypotheses with the drop-down boxes. The critical value, rejection region, test statistic, and $p-$value are computed and graphed. Different significance levels can be chosen with the drop-down box.
