Let us nd the moment generating functions of Ber(p) and Bin(n;p). For a Bernoulli random variable, it is very simple: M Ber(p)= (1 p) + pe t= 1 + (et1)p: A binomial random variable is just the sum of many Bernoulli variables, and so M Bin(n;p)= 1 + (et1)p n

WebYou must meet the following conditions for a binomial distribution: There are a certain number, n, of independent trials. The outcomes of any trial are success or failure. Each trial has the same probability of a success, p. Recall that if X is the binomial random variable, then X ~ B ( n, p ). WebThe Central Limit Theorem tells us that the point estimate for the sample mean, x ¯ x ¯, comes from a normal distribution of x ¯ x ¯ 's. This theoretical distribution is called the sampling distribution of x ¯ x ¯ 's.
