The formula given is for the standard error of the sampling distribution of a sample proportion, but $p$ should be the population proportion, not the sample proportion. The correct formula is $\sqrt { \frac { p ( 1 - p ) } { n } }$, where $p$ is the population proportion and $n$ is the sample size.
