At the conclusion of a second-year practical session, two groups of students engage in a heated debate. Group A students are certain that their results (Table 1) are statistically comparable to those obtained by Group B students (Table 2). Contrary to that, Group B students cannot possibly understand this and insist that their results are statistically different to those of Group A. Explain, with reasoning and carrying out all relevant calculations (assuming a 95% confidence level), whether you support Group A or Group B students. Table 1. Group A experimentally determined purity (% w/w) of paracetamol in commercial paracetamol samples by HPLC. Replicate % (w/w) 1 70.5% 2 70.8% 3 72.2% 4 70.6% Table 2.
