Question

Sapling Learning Calibration data for an electrochemical determination of glucose are in the following table. Because these data of magnitude, If plotted on a linear graph most of the points will be near the origin. A logarithmic plot overcomes this difficulty, leading to a more even distribution of the data. Glucose (ugimL) Current (nA) Glucose (ugi/mL) 3.01 Current (nA) 0.00813 0.0331 0.109 107 324 1020 3470 0.416 1.55 4.74 11.0 37.2 9.82 33.9 123 363 0.992 a) Plot log(nA) as a function of Number Determine the equation of the line in the form log(nA) = m, x logug/mL) + b. (b) What tion of Number glúcose coresponds to a signal of 87.9 nA? ? Hint
