Drinking-water quality study. Disasters (Vol. 28, 2004) published a study of the effects of a tropical cyclone on the quality of drinking water on a remote Pacific island. Water samples (size 500 milliliters) were collected approximately 4 weeks after Cyclone Ami hit the island. The following variables were recorded for each water sample. Identify each variable as quantitative or qualitative
(a) Town where sample was collected
(b) Type of water supply (river intake, stream, or borehole)
(c) Acidic level (pH scale, 1-14)
(d) Turbidity level (nephalometric turbidity units [NTUs])
(e) Temperature (degrees Centigrade)
(f) Number of fecal coliforms per 100 milliliters
(g) Free chlorine-residual (milligrams per liter)
(h) Presence of hydrogen sulphide (yes or no)
