Plot the following set on a scatter plot. Estimate the correlation and them compute it. Next identify any outliners in the following sets of data. Explain why you consider these to be outliners. Next recover those data points and re compute the correlation coefficient. What happens? What are the implication of this choice? Is it ethical to just remove these data points?
