question 228

Multiple Choice

TABLE 17-11
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) .
-Referring to Table 17-11,which of the following is the correct interpretation for the Tofel500 slope coefficient?

• A)Holding constant the effect of the other variables,the estimated mean value of school type is 0.39 lower when the school has a TOEFL criterion that is at least 550.
• B)Holding constant the effect of the other variables,the estimated school type decreases by 0.39 when the school has a TOEFL criterion that is at least 550.
• C)Holding constant the effect of the other variables,the estimated natural logarithm of the odds ratio of the school being a private school is 0.39 lower for a school that has a TOEFL criterion that is at least 550 than one that does not.
• D)Holding constant the effect of the other variables,the estimated probability of the school being a private school is 0.39 lower for a school that has a TOEFL criterion that is at least 550 than one that does not.
