A study was conducted to investigate variables associated with dropping out of high school.
The following logistic regression model was obtained:
Logit(Y i ) = 3.5 - 1.3X 1 + 2.3X 2 .

Y: 1 = dropped out of high school; 0 = did not drop out of high school;
X 1 : cumulative high school GPA obtained;
X 2 : 1 = retained in at least one grade; 0 = never retained in any grade.

-Based on logistic regression, if a student has been retained in at least one grade, the chance that he/she will drop out of high school
A) increases.
B) decreases.
C) stays the same.
D) is uncertain.

(The regression coefficient for X₂ is positive, indicating that if a student has been retained in at least one grade (X₂ = 1), the log odds of dropping out of high school will increase.)
