question 249

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 expression for the estimated model?

• A)Y = -3.9594 + 0.0028 SAT + 0.1928 Toefl90
• B) = -3.9594 + 0.0028 SAT + 0.1928 Toefl90
• C)ln (odds ratio)= -3.9594 + 0.0028 SAT + 0.1928 Toefl90
• D)ln (estimated odds ratio)= -3.9594 + 0.0028 SAT + 0.1928 Toefl90

Triglyceride levels measure the amount of triglycerides in the blood, important for assessing heart health and risk for cardiovascular diseases.

SPSS Output

Indicates the results generated by the Statistical Package for the Social Sciences (SPSS), used for analyzing and managing statistical data.

Wilcoxon Signed Rank Test

Utilized for comparing two related samples to determine if there are significant differences between their population mean ranks, especially when the population cannot be assumed to be normally distributed.

Null Hypothesis

The presumption of no significant difference or association in a set of data, serving as a default position in hypothesis testing until evidence suggests otherwise.
