Concerns about global warming have led to studies of the relationship between global temperature and the concentration
Question:
Concerns about global warming have led to studies of the relationship between global temperature and the concentration of carbon dioxide (CO2). Listed below are concentrations (in parts per million) of CO2 and temperatures (in C) for different years (based on data from the Earth Policy Institute). Is there a linear correlation between temperature and concentration of CO2?
Construct a scatterplot, find the value of the linear correlation coefficient r, and find the critical values of r from Table A-6 using ? = 0.05. Determine whether there is sufficient evidence to support a claim of a linear correlation between the two variables.?
