Scientists measured the blood glucose concentration of four groups of participants under different dietary trials. The results were represented in the format mean±standard deviation\text{mean} \pm \text{standard deviation}mean±standard deviation as follows:

  • Group A: 88.5±6.3 mmol/dm388.5 \pm 6.3\text{ mmol/dm}^388.5±6.3 mmol/dm3
  • Group B: 94.2±4.8 mmol/dm394.2 \pm 4.8\text{ mmol/dm}^394.2±4.8 mmol/dm3
  • Group C: 91.0±8.7 mmol/dm391.0 \pm 8.7\text{ mmol/dm}^391.0±8.7 mmol/dm3
  • Group D: 97.6±7.1 mmol/dm397.6 \pm 7.1\text{ mmol/dm}^397.6±7.1 mmol/dm3
