In an Early Study, Researchers at Ivy University Found That

Short Answer

In an early study, researchers at Ivy University found that 33 percent of the freshmen 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 freshmen, 185 had at least one A in their first semester. Calculate the p-value associated with the test statistic and test the claim at α = .05 using the p-value rule.
