Mr. Saksunn is concerned both about his students’ scores on the last math test, and about the number of students looking tired in class. He decides to see if there is a relationship between the number of tired or sleepy behaviors (yawns, nodding-off, head on desk) a student exhibits and their test score. He has his assistant observe
Make a scatterplot on graph paper and draw the line of best fit. Determine the equation of the line of best fit.
Place the Tired Behaviors on the
-axis and Test Score on the -axis for your scatterplot.
The test score is
. The number of tired behaviors is .
Using your equation from part (a), predict the test score of a student who exhibits
tired behaviors during Professor Saksunn’s math class in a week.
in for results in .
