How are hypotheses tested?

A. By developing theories

B. By collecting Data

C. By making educated guesses

D. By Reviewing what is known

Well i think the answer is B. the only way to test hypotheses is by preforming labs and experiments

When you first make a Hypothesis, you'll want to see if your Hypothesis is true or not. To do that, you must collect data to answer your Hypothesis, and maybe if you have collected enough to make a theory. Your answer is B. By collecting data. A would be the answer (but it's not in this case!) if you have already answered your Hypothesis, C is basically making a Hypothesis, and D is not testing your Hypothesis yourself.
