Null Hypothesis is the neutral hypothesis, stating no significant difference from assumed value. Alternate Hypothesis is the contradictory special hypothesis, stating significant difference from assumed value.

To Check whether 24 month old monkfish has actual weight = assumed average weight i.e 9.5lb, or less then that . The hypothesis are following :

surveys.

questionnaires.

interviews.

case studies.

participant and non-participant observation.
