question 335

Multiple Choice

TABLE 14-18
A logistic regression model was estimated in order to predict the probability that a randomly chosen university or college would be a private university using information on mean total Scholastic Aptitude Test score (SAT) at the university or college, the room and board expense measured in thousands of dollars (Room/Brd) , and whether the TOEFL criterion is at least 550 (Toefl550 = 1 if yes, 0 otherwise.) The dependent variable, Y, is school type (Type = 1 if private and 0 otherwise) .
The Minitab output is given below:
-Referring to Table 14-18, which of the following is the correct expression for the estimated model?

• A) Y = -27.118 + 0.015 SAT - 0.390 Toefl550 + 2.078 Room/Brd
• B) = -27.118 + 0.015 SAT - 0.390 Toefl550 + 2.078 Room/Brd
• C) 1n(odds ratio) = -27.118 + 0.015 SAT - 0.390 Toefl550 + 2.078 Room/Brd
• D) 1n(estimated odds ratio) = -27.118 + 0.015 SAT - 0.390 Toefl550 + 2.078 Room/Brd
