4. Below is the calibration curve of benzoic acid which was prepared as part of a validation exercise Standard concentration (mg/L) Absorbance 0.2 387 0.4 785 0.8 1533 1 1922 Calculate the slope and y-intercept based on the calibration data. Slope Y-intercept = Calculate syx based on the calibration data.sx/v = [E (Yi-Y'i)? / (n-2)]0.5 (a) (a) [2%) (b) [6%) (8%) (c) c Estimate the LOD and LOQ of benzoic acid. LOD of benzoic acid LOQ of benzoic acid
