Hypothesis Test for a Population Proportion



  • Use this test in practice when $np_0 \geq 10$ and $n(1 - p_0) \geq 10$.
Sample Size $n$:
Sample Proportion $\hat{p}$:
Null Hypothesis:$H_0: p=p_0=$
Alternative Hypothesis:$H_a:p$ $p_0$
Significance Level: $\alpha=$



Sample Size: $n=$
Sample Proportion: $\hat{p}=$
Standard Error: $\mbox{SE}_{\hat{p}}=$
Critical $z$ Value:$z^{*}=$
% Confidence Interval:
$z$ Statistic:$z=$
$p$ value:$p=$
