We would construct our confidence interval by taking x-bar and then adding, and subtracting, the value of the product of SDm and a t-value corresponding to our desired level of certainty and degrees of freedom (i.e. x-bar + (SDm) (t-value) and x-bar - (SDm) (t-value)).    From Wordnik.com.  [Conservapedia - Recent changes [en]] Reference
