The mean of the sampling distribution is always equal to the population proportion (p), and the standard deviation is calculated as sqrt (p (1 − p) / n), where n is the sample size. These measures are useful for understanding the distribution's center and spread, respectively, regardless of its shape.AP Stats: 6D, 6E, 6F.

Chi-squared tests require two familiar conditions for inference: When sampling without replacement, we should check the 10% condition for independence (n < 10%N) For our large counts condition, we need to verify that all of our expected counts are at least 5 (similar to other chi-square test set-ups). 🗼.
