Gladabjrken is developing a High-Performance Liquid Chromatography (HPLC) method to be

Gladabjrken is developing a High-Performance Liquid Chromatography (HPLC) method to be able to determine the amount of betulin in its betulin product Birch Gold (500 mg/L according to specification). In order to determine the concentration, they use a calibration curve, see below where SXX =5787; SY =289582 and SYX=40910. Under the analysis, you take 1ml of Birch Gold and dilute it to 10ml. The area obtained at the analysis of this betulin sample was 351 . a) Calculate the concentration of betulin in Birch Gold. b) Construct a 95% confidence interval for the betulin concentration in Birch Gold. c) Calculate the LoQ for the analytical method of Birch Gold (Hint consider dilutions)
