6. The data in the Table 6 were obtained during a colorimetric determination of glucose in blood serum. For each glucose concentrations $(0,2,4,6,8$ and $10\mathrm{mM})$, randomly select 2 results and answer the following questions. (a) Assuming a linear relationship between the variables, find the least-squares estimates of the slope and intercept. (b) Plot appropriate graphs and make comments about the adequacy of the model. (c) Determine the $95\%$ confidence intervals for the slope and intercept. (d) An unknown serum sample gave an absorbance of 0.413 . Find the glucose concentration in the sample. Glucose
