17 lip 2023 · A confidence interval for a mean is a range of values that is likely to contain a population mean with a certain level of confidence. We use the following formula to calculate a confidence interval for a mean: Confidence Interval = x +/- t* (s/√n) where: x: sample mean. t: the t critical value. s: sample standard deviation.
Description. Returns the confidence interval for a population mean, using a normal distribution. The confidence interval is a range of values. Your sample mean, x, is at the center of this range and the range is x ± CONFIDENCE.
