Comminution - Wikipedia

Comminution is the reduction of solid materials from one average particle size to a smaller average particle size, by crushing, grinding, cutting, vibrating, or other processes. In geology, it occurs naturally during faulting in the upper part of the Earth's crust. In industry, it is an important unit operation in mineral processing, ceramics, electronics, and other fields, accomplished with ...

Large Sample Estimation of a Population Mean

The Central Limit Theorem says that, for large samples (samples of size n ≥ 30), when viewed as a random variable the sample mean X-is normally distributed with mean μ X-= μ and standard deviation σ X-= σ ∕ n. The Empirical Rule says that we must go about two standard deviations from the mean to capture 95% of the values of X-generated by sample after sample.
