Introduction
Every year over the three days of Easter an international trout fishing competition is held on Lake Taupo.
Further information about the competition and trout can be found at these websites: http://www.mfe.govt.nz/publications/water/lm-fish-in-nz-lakes-jun02.pdf http://www.tongarirorivermotel.co.nz/trout-fishing/history-of-taupo-fishery/ http://www.taupofortomorrow.co.nz/fishery/trout.php Use the statistical enquiry cycle with this data to conduct a statistical investigation and write a report describing an investigation that uses statistical methods to make a formal inference related to the trout caught in the lake Taupo Fishing competition.
The data contains a list of all the trout weighed in during the Easter fishing competitions in 1997. This data is contained in the spreadsheet trout1997 .csv
The data was recorded by competition organisers. This data was used by the Department of Conservation to calculate the trout species populations in Lake Taupo.
