Based on the given data, plot the data as the optical absorbance of supernatant against the target Tbc concentrations, with the baseline signal level eliminated. Each point you plot should specify the average absorbance (A, no unit) for a particular Tbc concentration (C, unit: nM). Please add an error bar as the standard error for each average point. ans: Q2. Please compute the fitting line in the plot (for question 1) as a linear equation, i.e. A=kl*C+ ko, where kl and ko are the constants you need to figure out
