Question

practice it!
all of the following are true about hypotheses, except:
a hypothesis is based on background research performed by the
scientist.
a hypothesis is a statement that predicts what will be observed in
an investigation.
a hypothesis is usually written in an if-then format that describes
the proposed relationship between variables.
a hypothesis is a question a scientist wants to research.

Explanation:

A hypothesis is a prediction, not a question. It's based on research, predicts observations, and uses if - then for variable relationships. The option "A hypothesis is a question a scientist wants to research" is false.

Answer:

D. A hypothesis is a question a scientist wants to research (assuming the last option is D; if options are labeled differently, adjust the identifier, but the text is "A hypothesis is a question a scientist wants to research").
