A group of ten professional divers complete a cold-water survival trial to test thermoregulation. Medical researchers record the core body temperature of each participant immediately upon exiting the water.
| Diver | Core body temperature (∘C^\circ\text{C}∘C) |
|---|---|
| 1 | 34.6 |
| 2 | 35.2 |
| 3 | 34.9 |
| 4 | 35.0 |
| 5 | 34.5 |
| 6 | 35.1 |
| 7 | 34.8 |
| 8 | 35.3 |
| 9 | 34.7 |
| 10 | 35.4 |
Calculate the mean core body temperature of the ten divers. Give your answer to 1 decimal place.
If a diver's core body temperature is strictly below 35.0∘C35.0^\circ\text{C}35.0∘C, they are classified as hypothermic. What percentage of the divers would be classified as hypothermic?
