Assume that you have a box of resistors that have a Gaussian distribution of resistances with mean µ = 100 Ω and standard deviation σ = 20 Ω (i.e., 20% resistors). Suppose that you wish to form a subgroup of resistors with µ = 100 Ω and standard deviation 5 Ω (i.e., 5% resistors) by selecting all resistors with resistance between the two limits r1 = µ−a and r2 = µ+a. (Apparently, you are too cheap to just order the...
