WebIt can be shown (see Krishnamoorthy and Mathew 4) that a two-sided (1 – α, P) tolerance interval may be given as ( Xr , Xs ). Minitab chooses s = n - r + 1 so that r = ( n – k + 1) / 2. Both r and s are rounded down to the nearest integer. The actual or effective coverage is given by P ( V < k – 1). Notation Wilks, S. S.
