Using the following Concentration (X) and Intensity Values (Y), identify the best fit line calibration line. As you will note there is a clear deviation from linearity at some point. Use the r2 value to justify your choice and report this value as your answer. [X]=[0.0.58 1.16 1.74 2.32 2.9 3.49 4.07 4.65 5.23 5.81] [Y]=[ 9.09 21.65 38.98 54.57 74.92 90.95 106.97 123. 134.26 142.49 146.82]
