WebSep 14, 2024 · A confidence interval for a population proportion is a range of values that is likely to contain a population proportion with a certain level of confidence. 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 confidence level. WebA confidence interval corresponds to a region in which we are fairly confident that a population parameter is contained by. The population parameter in this case is the population mean \(\mu\). The confidence level is pre specified, and the higher the …
