A. What is the equation for the Linear Regression Line? Response area

B. There is a Response area correlation between the test marks and the homework marks.

C. The slope of the line of best fit can be used to make a probabilistic interpretation that states Response area



Options: No correlation, The homework mark increases 37 pts for every 1 pt. on the test mark, The test mark increases 1 pt for every 1 pt on the homework mark, the homework mark increases 0.89 points for every 1 pt. on the test mark, y = -37x + 1, y = 0.89x - 36.7, positive, y = 0.7x - 38, The test mark decreases 0.7 pts for every 1 pt on the homework mark. y = = -x + 37, Negative

Answer 1

To respond to your questions based on the linear regression analysis from the Desmos Graphing Calculator, here are the answers based on typical outcomes of linear regression:

A. What is the equation for the Linear Regression Line?

• Response: y = 0.89x - 36.7

B. There is a

• Response: positive correlation between the test marks and the homework marks.

C. The slope of the line of best fit can be used to make a probabilistic interpretation that states

• Response: The homework mark increases 0.89 points for every 1 pt. on the test mark.
