The one sample test of proportions compares an unknown proportion, \(p\), to a fixed value, \(p_0\). This calculator uses large sample theory, which relies on the convergance in distribution of a binomial random variable with parameter \(p\) ro a normal random variable with mean \(p\) and variance \(p (1 - p\)).

To input multiple values, seperate them by a comma.
