pooled estimate of variance. may be available that characterises the dispersion better than the estimated standard deviation obtained from a limited number of observations. If in such a case the value of the input quantity Q is determined as the arithmetic mean of a small number n of independent observations, the variance of the mean may be ...

The pooled sulfur reduction for moving nonroad diesel fuel from over 3500 ppm to below 500 ppm is substantially greater than the reduction of on-highway diesel fuel from 500 to 15 ppm. Reducing sulfur in nonroad and on-highway diesel fuels in two steps is potentially far more costly and disruptive than achieving those reductions at the same time.
