As previously stated, according to the United Nations the sustainability of oceans is under severe threat from pollution, and its effect on marine ecosystems via the process of eutrophication. Eutrophication causes excessive growth of plants and algae, affecting light and oxygen levels in oceans which further harms marine ecosystems. Consider the relationship between a country's Eutrophication measure (variable Chloro Y) and the log of the amount of beach pollution in that country (variable Beach_Lit X) from the data found in the QuestionD.xlsx file. Research Question: Is the log of the amount of beach pollution a useful predictor of the variable Chloro in a linear model analysis? Use the table, Excel data, and any other information provided perform an appropriate hypothesis test to address the research question and answer the following questions.
