A. The equation for the Linear Regression Line is y = 0.527x + 4.073.
B. There is a strong positive correlation between the test marks and the homework marks.
C. The slope of the line best fit can be used to make a probabilistic interpretation that states for every unit increase in the test mark, the homework mark is expected to increase by 0.527 units on average.
