A sample of 25 observations is taken to estimate a population proportion (pi). The sampling distribution of sample proportion p is
not normal since n < 30.
approximately normal because p is always normally distributed.
approximately normal if n 5 and n(1-) 5.
approximately normal if approaches 0.50.
