An alien spacecraft has crash landed on Earth and biologists were able to measure concen- trations of an unknown chemical as a function of radius from the crash-sight. The values of concentration (y) and radius (x) are as follows: X = [0.02] 0.10 0.32 0.66 [0.94] 1 y = [1.93 2.60 3.03 3.97 4.89 The biologists are turning to you to ask you to determine a line that best fits this data. That is, they want a best approximation to the problem y = ax + be where a, b eR are the constants to be solved for and e= 1 . Can you help Planet Earth?! Once you have solved for a, b, provide a plot that includes both the raw data (with circles or some comparable marker) as well as the best fit line through the data.
