t -Interval for a Population Mean. The formula for the confidence interval in words is: Sample mean ± ( t-multiplier × standard error) and you might recall that the formula for the confidence interval in notation is: x ¯ ± t α / 2, n − 1 ( s n) Note that: the " t-multiplier ," which we denote as t α / 2, n − 1, depends on the sample ... Oct 18, 2015 ... Note, if you want a critical value for a confidence interval, you would divide alpha by 2 since our confidence intervals are two-tailed in our
