Linear regression analysis was performed for the calibration standard data set based on this experiment. The analysis yielded the following results: m = 58.8746, b = -0.0063. What is the concentration of protein (mg/mL) in the original unknown protein solution if the measured absorbance is 0.669? The absorbance of a blank solution is 0.370. Assume a dilution factor of 40 for the analyzed unknown solution.
a) 0.1971
b) 0.207
c) 0.199
d) 0.2074
