What is a scientific hypothesis? a. a collection of data that generates a scientific observation b. a final decision that describes a scientific model c. a rigorous procedure that produces scientific data d. a statement that tries to answer a scientific question

The answer is D. A hypothesis is a statement that tries to answer is question but has not been proven to be correct yet.

After making the hypothesis, one can carry out these processes to testify that hypothesis.
