The Graduate Record Exam (GRE) is a standardized test required to be admitted to:
many
graduate schools in the United States. A high score in GRE makes admissions more likely.
According to the Educational Testing Service, the mean score for takers of GRE who do not have
training courses is 555 with standard deviation of 139. Brain Philippine (BP) offers expensive GRE
training courses, claiming their graduates score better than those who have not taken any training
courses. To test the company's claim, a statistician randomly selected 30 graduates of BP and
asked their GRE scores.
