In an Early Study, Researchers at a University Found That

In an early study, researchers at a university found that 33% of the first year students had received at least one A in their first semester. Administrators are concerned that grade inflation has caused this percentage to increase. In a more recent study, of a random sample of 500 first year students, 185 had at least one A in their first semester.
-The appropriate hypotheses that attempt to test the claim that the proportion of first year students receiving at least one A is now greater than one-third (.33) is _____.

A) H₀: p ≤ .37 vs H_a: p > .37
B) H₀: p ≥ .33 vs H_a: p < .33
C) H₀: p ≤ .33 vs H_a: p > .33
D) H₀: p = .33 vs H_a: p ≠ .33
E) H₀: p ≠ .33 vs H_a: p = .33
