This means that no two observations in a sample are related to each other or affect each other in any way. If you use a random sampling method to collect the data, this assumption is typically met.The 10% Condition says that our sample size should be less than or equal to 10% of the population size in order to safely make the assumption that a set of Bernoulli trials is independent. Of course, it's best if our sample size is much less than 10% of the population size so that our inferences about the population are as accurate as possible.AP stats vocab: 74 terms. atourville32.

Now look, we can take the number of successes/ failures to find the proportion of successes/failures in the sample: 20/50= 0.4. 0.4=p. 30/50=0.6. 0.6= 1-p. So essentially, we need to first check that the sample size is larger than 30. And if that is met, then we check if the number of successes/ failures in a sample are more than 10. Study with Quizlet and memorize flashcards containing terms like Large Counts Condition, 10% condition, standard critical value for 90% confidence and more. 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.🎥 Watch: AP Stats - Inference: Confidence Intervals for Proportions.
