Question

question 20 of 25
which statement best represents a hypothesis that could be
supported or not supported by evidence?

a. how does sleep affect a students performance on tests?

b. if students get more sleep, they will perform better on tests.

c. students who get more than eight hours of sleep will
feel better on the day of a test.

d. students should get more sleep if they want to do
well on tests.

Explanation:

To determine the hypothesis, we analyze each option:

• Option A is a question, not a hypothesis.
• Option B presents a testable relationship (sleep amount and test performance) that can be supported or refuted with evidence (e.g., by comparing test scores of students with different sleep durations).
• Option C focuses on "feeling better" which is more subjective and less directly testable for a hypothesis about test performance support.
• Option D is a recommendation, not a testable hypothesis.

Answer:

B. If students get more sleep, they will perform better on tests.
