BS 2846 2 is an international standard that specifies the statistical treatment of test results needed to calculate a confidence interval for the mean of a population. The scope of BS 2846 2 is limited to a special question. BS 2846 2 concerns only the estimation of the mean of a normal population on the basis of a series of tests applied to a random sample of individuals drawn from this population and
