About us. Large Counts Condition (one-sample) To check that the sampling distribution of p-hat is approximately normal, check that both the number of successes (n x p-hat) and the number of failures (n x (1-p-hat)) are at least 10 so that the sample size is large enough to support an assumption of normality

AP Statistics Unit 10 Comparing Two Populations or Groups. We use when estimating a difference in two proportions. No hypotheses are required. Uses random and large counts conditions. "P1 - P2 is the true difference in proportion of___". The conditions are random and large counts.Random Condition: so we can generalize to the population. 10% Condition: so sampling without replacement is OK. Large Counts/Normal Condition: so the sampling distribution of the sample proportions will be approximately Normal and we can use z to find a P-value. Don't reveal calculator commands yet.

This is known as The 10% Condition. The 10% Condition: As long as the sample size is less than or equal to 10% of the population size, we can still make the assumption that Bernoulli trials are independent.
