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, what should be the decision ('reject' or 'do not reject') on the null
hypothesis when testing whether Toefl500 makes a significant contribution to the model in the
presence of the other independent variables at a 0.05 level of significance?
