There are 48 pairs of students in the following table. Each pair has quantitatively determined the mass of caffeine in a 355 mL can of the popular energy drink marketed as “GRIME” using Liquid Chromatography-Mass Spectrometry (LC-MS). The class results are presented below. Summarise and report these results including an indication of measurement uncertainty. * Mass of Caffeine (mg) Mass of Caffeine (mg) (Table continued) 208.28 207.54 207.12 206.70 208.54 208.00 208.23 208.49 207.99 206.85 208.74 207.73 206.93 207.27 206.77 208.88 207.55 206.97 208.42 208.65 208.68 208.81 207.59 208.41 207.89 208.42 208.11 206.75 206.49 208.13 207.97 206.79 200.79 208.08 207.69 207.79 207.92 207.85 206.57 208.12 206.89 208.38 207.27 208.15 207.89 206.62 207.71 207.83
