13. Rob is a quality control specialist at a toothpaste factory. Part of his job is to verify that the filling machines are dispensing the proper amount of toothpaste into each tube. It is his first day working on a new machine that fills travel size toothpaste tubes.
The machine is supposed to produce an average fill rate of 0.85 ounces of toothpaste per tube.
: Rob randomly samples 16 of the 1000 travel size tubes of toothpaste that the machine produces that day. The weight, in ounces, of Rob's sample data is presented in the stem-and-leaf plot below. The stems are tenths of an ounce and the leaves are hundredths of an ounce.
