What is a hypothesis?
earnstyle [38]

Answer: D.) a suggested answer to a problem

Explanation:

A hypothesis is a supposition, suggested answer or a proposed explanation based on limited evidence which can be use to start an investigation. A hypothesis is more than a guess but less than a established theory and it can be tested through study and experiments.

<u>A hypothesis is part of the scientific method </u>because it is a prediction which can be tested and the results from those experiments may disprove a hypothesis, but can never entirely prove one.

It is not a conclusion because it is an idea which tries to explain an observation. It is not information collected from experiments because hypothesis are formulated before carrying out the experiments and it is not a widely accepted idea because it just proposes a tentative explanation about a phenomenon.
