The observed binomial proportion is the fraction of the flips that turn out to be heads. Given this observed proportion, the confidence interval for the true probability of the coin landing on heads is a range of possible proportions, which may or may not contain the true proportion.

The binomial distribution is the basis for the binomial test of statistical significance. [ 1 ] The binomial distribution is frequently used to model the number of successes in a sample of size n drawn with replacement from a population of size N .
Comparison of the rule of three to the exact binomial one-sided confidence interval with no positive samples. In statistical analysis, the rule of three states that if a certain event did not occur in a sample with n subjects, the interval from 0 to 3/ n is a 95% confidence interval for the rate of occurrences in the population.
In the theory of probability and statistics, a Bernoulli trial (or binomial trial) is a random experiment with exactly two possible outcomes, "success" and "failure", in which the probability of success is the same every time the experiment is conducted. [1]
Methods for calculating confidence intervals for the binomial proportion appeared from the 1920s. [6] [7] The main ideas of confidence intervals in general were developed in the early 1930s, [8] [9] [10] and the first thorough and general account was given by Jerzy Neyman in 1937.
The binomial distribution is the basis for the p-chart and requires the following assumptions: [2]: 267 . The probability of nonconformity p is the same for each unit;; Each unit is independent of its predecessors or successors;
It can be defined as the proportion of instances where the interval surrounds the true value as assessed by long-run frequency. [1] In statistical prediction, the coverage probability is the probability that a prediction interval will include an out-of-sample value of the random variable.
