Question

1)     The table below gives the amount of time students in a certain math class studied for a test and their test scores. Graph the data on a scatter plot, find the line of best fit, and write the equation for the line you draw.

Hours Studied	1	0	3	1.5	2.75	1	0.5	2
Test Score	78	75	90	89	97	85	81	80

 Linear Regression Equation: ____________________

     Correlation Coefficient (r): _________

      Type of Correlation: ______________________

        (positive, negative, none)

              Is the correlation strong? Explain

        Using the linear regression equation, predict

   a student’s test score if they studied for 4 hours. 

Answer 1

y = 5.42543 X + 76.40641
