(2) Google "finite population sampling" and you may find that a substantial amount of research has been done on sampling without replacement.
WebMar 10, 2024 · I have read this statement : Trials are independent (i.e. use binomial) if sampling is done with replacement. Trials are dependent (i.e. use hypergeometric) if sampling is done without replacemen... WebDefinition 3.4.1. Suppose in a collection of N objects, m are of type 1 and N − m are of another type 2. Furthermore, suppose that n objects are randomly selected from the collection without replacement. Define the discrete random variable X to give the number of selected objects that are of type 1. Then X has a hypergeometric distribution ...
WebWe can also prove this identity algebraically, using the binomial theorem, $(a+b)^n=\sum_{k=0}^{n} {n \choose k} a^k b^{n-k}$. If we let $a=b=1$, we obtain $2^n=\sum_{k=0}^{n} {n \choose k}$. To show this identity, let's assume that we have an arbitrary set $A$ with $n+1$ distinct elements: $$A=\{a_1, a_2, a_3, ...,a_n,a_{n+1}\}.$$ … WebJun 19, 2024 · Sampling without replacement can cause the probabilities from each trial to fluctuate slightly from each other.

In probability theory and statistics, the binomial distribution with parameters n and p is the discrete probability distribution of the number of successes in a sequence of n independent experiments, each asking a yes–no question, and each with its own Boolean-valued outcome: success (with probability p) or failure (with probability ). A single success/failure experiment is also called a Bernoulli trial o…
