An exercise physiologist is investigating whether a new high-intensity interval training (HIIT) protocol improves aerobic capacity (VO2 max\text{VO}_2\text{ max}VO2 max, measured in ml/kg/min\text{ml/kg/min}ml/kg/min) more than a traditional continuous endurance training (CET) protocol. Eight participants perform the HIIT protocol, while another group of eight participants perform the CET protocol. After six weeks, their peak VO2 max\text{VO}_2\text{ max}VO2 max scores are measured. The data collected is shown in the table below.
| VO2 max\text{VO}_2\text{ max}VO2 max scores (ml/kg/min\text{ml/kg/min}ml/kg/min) | Traditional CET group | ||||
|---|---|---|---|---|---|
| New HIIT group | |||||
| Participant | Score | Rank | Participant | Score | Rank |

Explain what p<0.01 p < 0.01\,p<0.01 would mean if it appeared as part of the significance statement when reporting the findings from this study.
