Answer ALL parts of this question Liquid chromatography with UV detection has been used to quantify quinine. In an experiment to determine the best protocol for generating a calibration curve, the following data was obtained. Quinine Concentration (mg/L) Peak area 0.5 50 0.8 82 1 95 1.2 119 1.5 150 (a) Calculate the correlation coefficient (r) and the equation of the calibration curve. (5 marks) (b) Justify statistically if the concentrations and peak areas are correlated with a level of confidence of 95%. (5 marks) (c) Quantify the concentration of quinine for which a peak area of 105 was obtained. (5 marks) (d) Indicate, briefly, which data could be used to assess the sensitivity of the developed method; and explain what information can be obtained from the assessment of residuals of a calibration curve
