The study "Determinants of Board Exam Results in Engineering" specifically aims to determine the linear relationship of Board Exam Score (BScore) and Entrance Exam Score in College (EScore). A correlation and regression analyses were used in the study and obtained the following results:

Correlation analysis: r = 0.924

Simple Linear Regression: a = 25.17 b = 0.677

Which of the following best describe the slope of the regression line?

a.) The slope of the regression line suggests that a 1 unit increase in the EScore there is 0.667 unit increase in BScore.

b.) The slope of the regression line suggests that a 1 unit increase in the BScore there is 25.17 unit increase in EScore.

c.) The slope of the regression line suggests that a 1 unit increase in the EScore there is 25.17 unit increase in BScore.

d.) The slope of the regression line suggests that a 1 unit increase in the BScore there is 0.667 unit increase in EScore.
