Bugs Be Gone ( Cidney Marbella )


In 2005, after Hurricane Katrina, there was a lot of wet swampy areas in New Orleans. Wet and Swampy attracts bugs. People don't like bugs. Bugs are killed by pestecides. In this study, we looked at the effectiveness of a certain "bug buster" pesticide, and it's effectiveness on all areas. We got that 22% mortality rate in a specific area, indidcates that the pesticide kill all 22% of pests in all areas.



State: A 22% mortality rate indicates that the pesticide killed 22% of the pests in the treated area.

Plan: Random: Randomly Treated Area's
        10% 10 Area's affected by pests is less than 10% of all area's affected by pests


Simple linear regression results:
Dependent Variable: Rate in which they die ( Mortality Rate)
Independent Variable: Cocentration of Bug Buster )percentage) 
Rate in which they die ( Mortality Rate) = 0.11533333 + 0.046242424 Cocentration of Bug Buster )percentage)
Sample size: 10
R (correlation coefficient) = 0.95039759
R-sq = 0.90325559
Estimate of error standard deviation: 0.097198641

Parameter estimates:

Slope 0.046242424 0.0053506091 ≠ 0 8 8.6424599 <0.0001

Analysis of variance table for regression model:
Model 1 0.70565939 0.70565939 74.692113 <0.0001
Error 8 0.075580606 0.0094475758    
Total 9 0.78124      

  Conclusion: The graph and data indicate that it 22% of mortality rate doesnt not mean a 22% mortality rate in all areas. Regardless of the correlation (0.95039759), correltation does mean causation.
