Final answer:
The 5 criteria for impending danger threshold include potential for extreme physical danger, uncertainty over whether a serious fire or hazard awaits after an alarm, the need to satisfy certain criteria for a measurement or observation to be believed, the consideration of strictness for expected and unexpected results, and knowing the meaning of common hazard signs.
Step-by-step explanation:
The 5 criteria for impending danger threshold include:
- Potential for extreme physical danger.
- Uncertainty over whether a serious fire or hazard awaits after an alarm.
- The need to satisfy certain criteria for a measurement or observation to be believed.
- The consideration of the strictness of criteria for expected and unexpected results.
- Knowing the meaning of common hazard signs.
For example, the hypothesis that states the number of deformed frogs in ponds polluted with chemical X is higher than those without chemical X satisfies the criteria.
