The CONFIDENCE (alpha, sigma, n) function returns a value which you can use to construct a confidence interval for a population mean. It is assumed that the sample data follow a standard normal distribution with known standard deviation sigma, and the sample size is n. Alpha is a small probability, such as 0.05, and 0 < alpha < 1. For a 95% confidence level, alpha is calculated as 1 â 0.95 = 0.05.
