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).
-True or False: Referring to Table 17-11,there is not enough evidence to conclude that Toefl500 makes a significant contribution to the model in the presence of the other independent variables at a 0.05 level of significance.

Quizplus · Accepted Answer

Based on the p-value for Toefl550 in Table 17-11, which is 0.058, we cannot reject the null hypothesis that the coefficient for Toefl550 is zero at the 0.05 level of significance. Therefore, there is not enough evidence to conclude that Toefl550 makes a significant contribution to the model in the presence of the other independent variables at a 0.05 level of significance.
