Question

b. the hypothesis:
your little sister asks you a scientific question: \does chocolate milk come from brown cows?\ in order to answer the question, you decide to form a hypothesis.
explain whether or not the following statements are effective hypotheses.

i. brown cows produce chocolate milk. (1 point)

ii. brown cows never produce chocolate milk. (1 point)

iii. brown cows produce white milk. (1 point)

Explanation:

• For a hypothesis to be effective, it should be testable.
• i. "Brown cows produce chocolate milk" is a testable statement as one can check (by observing, researching dairy processes etc.) if brown cows indeed produce chocolate - milk.
• ii. "Brown cows never produce chocolate milk" is also testable. One can look at the milk production of brown cows (through experiments, surveys of dairy farms etc.) to verify this statement.
• iii. "Brown cows produce white milk" is not directly related to answering the question "Does chocolate milk come from brown cows?". The original question is about the origin of chocolate milk, and this statement is about the color of milk from brown cows which may not be relevant to the chocolate - milk origin question.

Answer:

• i. Effective hypothesis.
• ii. Effective hypothesis.
• iii. Not an effective hypothesis for answering the given question.
