Complex Samples Z-Test of a Proportion

Where $g$ is the observed proportion, $e$ is the expected proportion, $s_{p}$ is the estimated Standard Error of the observed proportion and $n$ is the sample size,

$n$ is the sample size:

$z={\frac {g-e}{s_{p}}}$

where $p=2(1-\Phi (|z|))$ if $g\neq e$ and NaN otherwise.
