[4/4] One оf the mаjоr pushes tоwаrds renewаble bio-fuels is the use of algae to generate energy-containing oils that can substitute for oils generated from fossil fuels. One of the limitations of this work currently is the ability to scale up… in other words the ability to move towards a scale of mass-production such that huge quantities of the algae fuels can be produced in a cost-efficient manner. A scientist observes that algae blooms occur more frequently in ponds polluted with fertilizers. Understanding that one of the major ingredients of a fertilizer is nitrogen, the scientists decides to see if increasing nitrogen supplementation in the algae tanks will increase the production of algae bio-fuels. The scientist uses 4 separate small-scale tanks of algae, one with standard levels of nitrogen, and the other 3 tanks with increasing amounts of nitrogen, above the normal control levels. After 2 weeks of growth, total amounts of bio-fuel produced in each tank is similar. Even without seeing the direct statistics, would you guess that the null hypothesis of this study was rejected or accepted (2 point)?
