The presence of mercury in fish is a health concern for people who eat them, especially for women who are or may become pregnant, nursing mothers, and young children. This problem is concerned with mercury contaminant in Atlantic cod (Gadu morhua) caught at the location of 68 12'0" N, 14°48'0" E, North Atlantic. There are three selected attributes, age, body length, and the output is the mercury level in the fish muscle, as shown in Table 1. It is generally known that mercury concentration increases if age and/or body length increase.

Transcribed Image Text:The presence of mercury in fish is a health concern for people who eat them, especially for
women who are or may become pregnant, nursing mothers, and young children. This
problem is concerned with mercury contaminant in Atlantic cod (Gadu morhua) caught at
the location of 68 12'0" N, 14°48'0" E, North Atlantic.
There are three selected attributes, age, body length, and the output is the mercury level in
the fish muscle, as shown in Table 1. It is generally known that mercury concentration
increases if age and/or body length increase.
