2. Study of quality of drinking water. Disasters (Vol. 28, 2004) published a study of the effects of a tropical cyclone on the quality of drinking water on a remote Pacic island. Water samples (size 500 millilitres) were collected approximately four weeks after Cyclone Ami hit the island. The following variables were recorded for each water sample: Identify each variable as quantitative or qualitative. (a) Type of water supply (river intake, stream, or borehole) Qualitative (b) Acidic level (pH scale, 1 to 14) Quantitative (c) Turbidity level (nephalometric turbidity units NTUs) Quantitative (d) Temperature (degrees centigrade) Quantitative (e) Presence of hydrogen sulphide (yes or no) Qualitative
