A geologist hypothesizes that higher altitudes result in a lower boiling point for water due to decreased atmospheric pressure. Altitude (m) | Boiling Point (^circC) 0 (Sea Level) | 100.0 1,000 | 96.7 2,000 | 93.4 3,000 | 90.1 Which statement evaluates the hypothesis based on these findings?

1. The hypothesis is supported because the experiment reached a maximum altitude of 3,000 meters safely.
2. The hypothesis is refuted because water must reach 100^circC to boil regardless of the external altitude.
3. The hypothesis is refuted because the atmospheric pressure was not measured or recorded in the data table.
4. The hypothesis is supported because the boiling point decreases by approximately 3.3^circC for every 1,000 m of altitude.
