Question 1121317: What if your sample is less than 30 and you don't know the population mean or standard deviation, but you know the sample stats, x-bar and s, and that the sample is from a normal population.

a t-distribution with degrees of freedom n-1
This works when the population may be considered normally distributed and the standard deviation of the sample, s, may be considered a decent estimator (or unbiased outright) of the population standard deviation.
