Understand the four binomial setting requirements and associated vocabulary. Recognize when it might be reasonable to describe a random phenomenon as binomial. The distribution of a count depends on how the data are produced. The binomial setting: there are a fixed number n of observations (attempts, the n observations are all independent. The count x of successes in the binomial setting has the binomial distribution with parameters n and p. the parameter n is the number of observations, and p is the probability of a success on any one observation. The possible values of x are the whole numbers from 0 to n. Imagine a doctor overseeing n single-birth deliveries as a binomial setting.
