BackgroundBackground: Coral reef ecosystems are at risk world-
wide from a variety of anthropogenic and natural factors. Many countries have established marine protected areas where human activities such as fishing, tourisms, and harvesting of marine resources are limited. The effectiveness of marine protected areas varies widely, depending on the level of enforcement and protection.
The goal of this research project is to investigate the influence of the Hol Chan Marine Reserve on the fish community.

The Grunts – (counted by Ms. Quillen and Mrs. Seman)

QuestionDoes the Hol
Chan Marine Reserve have an effect on the numbers of fish found inside the reserve compared to outside the reserve?

Our HypothesisHA: There will be greater numbers of grunts
in Hol Chan Marine Reserve as compared to outside the Marine Reserve. (Accepted Hypothesis)
HO: There will be equal numbers of grunts in Hol Chan Marine Reserve as compared to outside the Marine Reserve. (Null Hypothesis)

PredictionsIf HA is true, then we will see a significant
difference in the amount of grunts counted inside the Marine Reserve and outside the Marine Reserve.
If HO is true, then we will see no significant difference in the amount of grunts counted inside the Marine Reserve and outside the Marine Reserve.

ConclusionWe reject HA and accept HO there is no
significant difference in numbers of grunts inside and outside the Marine Reserve.
Our p value is 0.272301To accept HA, p value must be < 0.05
