1.1 Diabetes insipidus (dilute urine) is a disease caused by a lack of ADH secretion into plasma. Scientists wanted to determine the effect of this disease on the volume of urine that a person produces per day. The investigation was carried out on 5 male participants over a period of 30 days. The males were of similar age
and weight. Their average daily urine production was calculated and recorded in the table below.
NOTE: Normal daily urine production is between 600 mf — 1800 mt
