Rainfall -0.055 0.408
Temperature 0.104 0.331
Relative Humidity -0.308 0.094
Source: Calculated Values
The table 2 reveals that there is a negative correlation between rainfall and total fish production though the value is not significant. The temperature does not affect fish production and humidity makes negative changes in fish production. But the values are not significant.
The following multiple regression equations with their respective R2 values express the contribution of both rainfall, temperature and humidity on the production of fish in the study area.
MFP = -15758 + 0.033X1 + 0.20X2 - 0.35 X3 R2 = 0.125
MFP = Marine Fish Production X1 = Rainfall
X2 = Temperature X3 = Mean Relative Humidity
The regression equation meant for fish shows that if the rainfall increases by one unit, the marine fish production increases by 0.03 unit and the fish production increases by 0.20 unit as the temperature increases by one unit. However, one unit change in humidity makes 0.35 unit decrease in the fish

My indiviidual project was based on the decay of HIV/AIDS, but the number of new cases of HIV/AIDS only decreases very slightly each year in the U.S., .03% to be exact. I based my equation on the number of new cases in 2010 and 2012, which gave me the equation of y=47,500(.997)X. 47,500 was the starting number or the number of cases in 2010, I got the number .997 by subtracting the rate (.003) from the number 1, and the x represents a

Ocean Acidification Essay
861 Words | 4 PagesThe topic of this research paper will cover over Ocean Acidification and the effects on marine ecosystems. Ocean acidification is the decrease in pH levels of the Earth 's oceans, due to overbearing carbon dioxide being brought by the atmosphere. The carbon dioxide is drawn by seawater, where the chemical reactions take place, which minimize the pH levels in the ocean, the carbonate levels and the important calcium carbonate which these sea creatures need. When carbon dioxide disperses in this ocean, it causes the levels of acidity to rise towards the the surface, where most shell growth in marine animals have been stopped and has created the cause of reproductive disorders in multiple fish. Part of the problem with ocean acidification is human activity.
