T Number of consignments loads). •
nmin, nmax Minimum and maximum load size (n. of items). •
μ, σ Gaussian parameters for the (individual) item. •
Data delimiter       (See below.) Delimiter (character). •
.seed RNG seed (iff 0, nonrepeatable). •
Show values Show the graph coordinates.

By simulating loads of sizes in [nmin, nmax], random discrete uniform, creates a file with T sample sums and their sizes, from which the average can be calculated. The items are considered Gaussian, μ, σ .

This supplies what could be industrial lists, such as records of truck weights with known (unequal or equal) numbers (sample size) of bags.

Data delimiter — The delimiter chosen is applied to separate the two values ('sample sum', 'sample size') in each row, producing: (i) space, a matrix table; (ii) tab, a copy-paste spot; (iii) ';' (semicolon), a Euro. 'csv' file; (iv) ',' (comma), an Amer. 'csv' file.

Draws plots of: the averages, and the estimated μ (for the individual values),
