WebIf X is a binomial random variable, then X ~ B ( n, p) where n is the number of trials and p is the probability of a success. To form a proportion, take X, the random variable for the number of successes and divide it by n, the number of trials (or the sample size). The random variable P′ (read “P prime”) is that proportion, P ′ = X n P ... WebSep 14, 2024 · The formula to calculate this confidence interval is: Confidence interval = p +/- z* (√ p (1-p)/n) where: p: sample proportion. z: the z-critical value based on the …
