Describe the slope of the graph. What does it imply about studying and test scores?
Most of the students that had an A on the test (90 or above), studied for at least 180 minutes. If you also studied for 180 minutes, would you get an A on the test?
Would you say that the more time studying guarantees that you would get a better test grade?
One person did not study at all and still received a passing grade of 65 (D). Based on the trendline, what would have been the predicted grade of the student that did not study?
Quantify how your previous answer compares to the actual grade of 65.
