SCENARIO 17-11 A Logistic Regression Model Was Estimated in Order to Predict

question 116

Multiple Choice

SCENARIO 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) .
The Minitab output is given below:
-Referring to Scenario 17-11, which of the following is the correct interpretation for the SAT slope coefficient?

• A) Holding constant the effect of the other variables, the estimated mean value of school type increases by 0.015 for each increase of one point in average SAT score.
• B) Holding constant the effect of the other variables, the estimated school type increases by 0.015 for each increase of one point in average SAT score.
• C) Holding constant the effect of the other variables, the estimated probability of the school being a private school increases by 0.015 for each increase of one point in mean SAT Score.
• D) Holding constant the effect of the other variables, the estimated natural logarithm of the odds ratio of the school being a private school increases by 0.015 for each increase of one Point in mean SAT score.
