The membrane filter technique was used to test a polluted water for the coliform group. Three different water sample volumes (5 ml, 50 ml, and 500 ml) were filtered through five filter membranes. The colony counts were as follows: 5 ml membranes: 4, 8, 5, 2, 3 50 ml membranes: 24, 38, 25, 32, 30 500 ml membranes: 250, 320, 360, 210, 280 a. What are the most valid data obtained? b. Calculate the...
