From there, it utilizes the t/z score formula to calculate the interval fifty percent that flank the sample mean. Enter std. Note: Prior to March 1st 2006, this calculator computed this interval by adding one z-value to the numerator and a squared z-value to the denominator. Assuming the following with a confidence level of 95%: X = 22.8. If you either graph both intervals on a number line or position them relative to one another, note that there is no overlap of the two and the entire interval from 1978 is larger than the entire interval from last year.
