Large counts condition ap stats.

10% condition - observations can be considered independent as long as the sample size is less than 10% of the population. Large Counts condition - when the expected number of success and failures are both greater than or equal to 10, the binomial distribution can be approximated using a Normal distribution. Formulas for the mean and …Step-by-step explanation. For first sample, number of success and failures is not at least. Success = 16 > 10. and. failure = 25 - 16 = 9 < 10 (condition failed) Therefore, we cannot use the method because the condition of large count or success failure is not satisfied.
