Interval Estimates - University Of Regina
In practice σ is rarely known and in note 1, p. 299, ASW state this. In addition, as n increases, the t-distribution approaches the normal distribution. Thus, so long as n > 30, it is acceptable to use s as an estimate of σ for purposes of constructing an interval estimate. ... Get Content Here
