Extracted text: 3. Because a great number of applicants, Ms. Lawrab, Dean of Admissions at Private University, must establish a new standard for admission. It was suggested that she turn down anyone who's College Board scores averaged less than 600, bus some of the admissions committee believe that there is no significant difference between previously admitted students who averaged 600 or more and those who averaged under 600in their potential to graduate. To determine who was right, they took a random sample of records of students who entered the university 5 years ago. Graduated Withdrew Flunked Out Total Voluntarily Scored 600 or more 48 7 60 46.5 7.5 Scored under 600 76 13 11 100 77.5 12.5 10 Total 124 20 16 160 Do the data present enough evidence to establish that 600 is a good cutoff point for admission? (Le Is there a relationship between the College Board Score and graduation?) Test as the 0.1 significance level.
