The Beer-Lambert law relates the absorbance A of a solution to the concentration C of a species

Question:

The Beer-Lambert law relates the absorbance A of a solution to the concentration C of a species in solution by A = MLC, where L is the path length and M is the molar absorption coefficient. Assume that L = 1 cm. Measurements of A are made at various concentrations. The data are presented in the following table.

a. Let A = β0 + β1C be the equation of the least-squares line for predicting absorbance (A) from concentration (C). Compute the values of β0 and β1.
b. What value does the Beer-Lambert law assign to β0?
c. What physical quantity does β1 estimate?
d. Test the hypothesis H0: β0 = 0. Is the result consistent with the Beer-Lambert law?
