Mr. Jon Molnar will graduate from Eastwood High School this year. He took the American College Test (ACT) FOR COLLEGE ADMISSION AND RECEIVED A SCORE OF 30. the high school principal informed him that only 2 percent of the students taking the exam received a higher score. The mean score for all students taking the exam is 18.3. Jon's friends Karrie and George also took the test but were not given any information by the principal other than their scores. Karrie scored 25 and george 18. Based on this information, what were karrie's and George's percentile ranks? What assuption is necessary?
