Recall that a confidence interval is calculated using the sample mean and a margin of error. The margin of error will vary depending on the level of confidence α, the population standard deviation σ, and the size of the sample n. This value will be added to and subtracted from the sample mean, x, using the following formula where zα/2 is the value of z that gives an area of α 2 in the upper tail of the standard normal probability distribution.
