A species of marine arthropod lives in sea water that contains calcium in a concentration of 32 mmole/kg of water. Thirteen of the animals were collected and the calcium concentrations in their coelemic fluid found to be: 28, 27, 29, 30, 30, 31, 30, 33, 27, 30, 32, 29 and 31 mmole/kg. Test the hypothesis to conclude whether members of this species maintain a coelemic calcium concentration less than that of their environment
