13. A poll for Tylenol PM indicated that 7% of American students have missed a test because they overslept. Suppose officials at a state college decide to apply a new academic policy regarding exams. If a student arrives late for a test, then the student receives a 0 for the test and cannot take a make-up test at a later time.

13(a). What hypotheses should be tested, in terms of p, the true proportion of students who have missed a test because they overslept, in order for college officials to prove that the new academic policy is causing fewer students to be late for exams?

H₀: p = 0.07 H_a: p [ Select ] ["", ">", "<"] 0.07
