Question 3 Curt determines the concentration of Propranolol in samples using an LC method. The method consists of a calibration curve where known Propranolol concentrations are plotted against the peak height of the Propranolol peak, see table below. Curt performed four measurements on the same sample solution. The peak heights of these measurements were: 253,279,265 and 255mV. To facilitate your calculations, I provide the following sums: SXX=0.01488,SYY=646880 and SXY=98.08. a) Perform linear regression using the specified sums of calibration data above. Also calculate R2 for your fit. b) Construct a 95% confidence interval for Propranolol in the sample solution. Don't forget to remove any outliers, answer in g/L
