Question

what is the primary difference between a scientific theory and a hypothesis? a theory is used for a single experiment, while a hypothesis explains a wide range of observations. a theory is a well-tested explanation, while a hypothesis is a proposed explanation that has not yet been widely confirmed. a hypothesis is a proven fact, while a theory is just an educated guess. a hypothesis is a well-supported idea, while a theory is a simple observation.

Explanation:

To determine the correct answer, we analyze the definitions of scientific theory and hypothesis:

• A scientific theory is a well - tested explanation that is supported by a large body of evidence and explains a wide range of phenomena. A hypothesis is a proposed explanation (an educated guess) that has not yet been widely confirmed through extensive testing.
• Let's analyze each option:
• Option 1: Incorrect. A theory is not for a single experiment, and a hypothesis can potentially explain more than one observation as it is tested.
• Option 2: Correct. This matches the definitions: a theory is well - tested, a hypothesis is a proposed explanation not yet widely confirmed.
• Option 3: Incorrect. A hypothesis is not a proven fact, and a theory is not just an educated guess. Theories are well - supported by evidence.
• Option 4: Incorrect. The descriptions are reversed. A hypothesis is a proposed (not well - supported) idea, and a theory is well - supported, not a simple observation.

Answer:

The second option (the one with the text "A theory is a well - tested explanation, while a hypothesis is a proposed explanation that has not yet been widely confirmed.")
