A spectrometer that emits light is shined on a solution that contains a liver sample, and the amount of light absorbed is recorded. The above procedure was tried on five samples having known amounts of protein, with the following data resulting: Light absorbed 0.32, 0.98, 1.21, 1.53, 1.81 Amount of protein 2, 16, 30, 46, 55 Find the sum of squares of the residuals SSR, the coefficient of determination R2, and the sample correlation coefficient r
