## Binomial distribution confidence interval online

Normal Approximation Method of the Binomial Confidence Interval. The equation for the Normal Approximation for the Binomial CI is shown below. where p = proportion of interest. n = sample size. α = desired confidence. z 1- α/2 = “z value” for desired level of confidence. z 1- α/2 = 1.96 for 95% confidence. For X with Binomial (n, p) distribution, Section 1 gives a one-page table of .95 and .99 confidence intervals for p, for n = 1, 2, …, 30. This interval is equivariant under X → n − X and p → 1 − p, has approximately equal probability tails, is approximately unbiased, has Crow's property of minimizing the sum of the n + 1 possible lengths, and each of its ends is increasing in X and Binomial confidence interval calculation rely on the assumption of binomial distribution. For example, a binomial distribution is the set of various possible outcomes and probabilities, for the number of heads observed when a coin is flipped ten times. This confidence interval calculator for proportions helps to find the sample confidence interval for proportion. The standardised ‘Wald’ confidence interval employs the Normal approximation to the Binomial distribution sketched in Figure 1. The actual distribution, shown by the columns, is assumed to be a discrete Binomial distribution, but to obtain the interval we first approximate it to a continuous Normal curve, shown by the line.
