摘要: The problem of hypothesis testing about proportions in two finite populations is addressed. usual test based on the normal approximation (Z test) and a estimated p values (E are considered. exact properties tests evaluated numerically. Numerical studies indicate that E very satisfactory even for small samples can be recommended practical use. Power computation given level sample size also outlined both tests. methods illustrated using an example.
