New method for blood typing. In Analytical Chemistry

(May 2010), medical researchers tested a new method of typing blood using low cost paper. Blood drops were applied to the paper and the rate of absorption (called blood wicking) was measured. The table gives the wicking lengths

(in millimeters) for six blood drops, each at a different antibody concentration. Construct a plot to investigate the relationship between wicking length and antibody concentration.

What do you observe?
