Based on the assumed probable error range in Table 1, the followings in Table 3 are the lower ([c.sub.a]), middle ([c.sub.m]) and upper ([c.sub.b]) bound values, and also the expected value ([c.sub.e]) and variance ([s.sup.2]) for each cost element.
For dense medium cyclones treating coal in the size range -13.0 + 0.5mm, the probable error ranges from 0.02 to 0.03 which is very sharp when compared with the performance of a Batac jig treating the same size range of coal: the probable error for this separation would range from 0.07 to 0.10.
