When you have averaged measurements for two items, what is the probability the one with the larger mean is actually the smaller, assuming normal distributions? That is, what is the chance that green is greater than yellow here? (without requiring the σ's to be equal). — kwami ( talk) 01:41, 8 January 2014 (UTC)
Has there been any mathematical study of the "optimum" lengths for a gauge block set? What do you call such a set of lengths?
I'm looking for something analogous the way different ways of "optimizing" the marks on a ruler lead to different kinds of sparse ruler. And analogous to the way various ways of "optimizing" other sets of things leads to various sets of numbers called preferred number. -- DavidCary ( talk) 20:02, 8 January 2014 (UTC)
