Fact or Guess: Hypotheses and The Scientific Method John Storrs SC235 Unit 1 January 10, 2012 Kaplan University Professor Travis Kibota Hypotheses and The Scientific Method Assignment Question 1: Read the scenario below and then analyze what is wrong with the hypothesis given. Renee has noticed that a few of her friends have better eyesight than she does. She watches what they eat and then decides to come up with a hypothesis.
