A sample consisting of 10 cartons of Arrow water was taken to measure the degree of salts in the water and the results were shown as follows) = 4.1, 3, 7,5.2, 6.2, 6.1, 5.7, 7, 3.4, 6.5 and whether the production is being used. Find the arithmetic mean panels for single measurements, the upper bound and The limit is the one.
