SCENARIO 14-18 A Logistic Regression Model Was Estimated in Order to Predict

question 156

Short Answer

SCENARIO 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). There are 80 universities in the sample. The PHStat output is given below:

-Referring to Scenario 14-18, what is the p-value of the test statistic when testing whether SAT makes a significant contribution to the model in the presence of Toefl90?

Definitions:

Circular DNA

DNA that is structured in a loop or circle, commonly found in bacteria and some eukaryotes, distinct from the linear DNA of most eukaryotic organisms.

Linear DNA

DNA molecules that exist in a straight or linear form, as opposed to circular DNA found in some bacteria and the mitochondria of eukaryotes.

Unwound Chromatin

Refers to the relaxed form of chromatin, making it accessible for processes like transcription and replication.

Nucleosomes

Repeating units of chromatin structure, each consisting of a length of DNA wound around a complex of eight histone molecules. Adjacent nucleosomes are connected by a DNA linker region associated with another histone protein.
