question 182

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 and whether the TOEFL criterion is at least 90 (Toefl90 = 1 if yes,0 otherwise) .The dependent variable,Y,is school type (Type = 1 if private and 0 otherwise) .
The PHStat output is given below:
-Referring to Table 14-18,which of the following is the correct interpretation for the Toefl90 slope coefficient?

• A)Holding constant the effect of SAT,the estimated mean value of school type is 0.1928 higher when the school has a TOEFL criterion that is at least 90.
• B)Holding constant the effect of SAT,the estimated school type increases by 0.1928 when the school has a TOEFL criterion that is at least 90.
• C)Holding constant the effect of SAT,the estimated natural logarithm of the odds ratio of the school being a private school is 0.1928 higher for a school that has a TOEFL criterion that is at least 90 than one that does not.
• D)Holding constant the effect of SAT,the estimated probability of the school being a private school is 0.1928 higher for a school that has a TOEFL criterion that is at least 90 than one that does not.
