There seems to be a linear relationship but not enough to say it is when first testing if there was relationship, because the line slightly toughed one of the point (Y=1.39E2+2.48*x). There seem to be increasing relation between continine and cigarettes per day. But as we test further there seems to be no relation between continine and cigarettes per day on the scatterplots.
When finally running the correlation test there was a positive correlation coefficient relation between the two variables. Meaning that when cigarettes per day increase, so does cotinine. When running the test of the rank we get the same results. Therefore, the relation between cigarettes per day and continine is positive relationship between them both because correlation
