desmos graphing calculator: use the link to access the graphing calculator. open a table and input the data. ask the calculator for a linear regression line
a. what is the equation for the linear regression line?_
b. there is a _ 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 states. _
a. The equation for the linear regression line is y = 0.5407x + 12.0697.
b. There is a moderate 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 stating that for every increase of 1 unit in the test marks, there is an average increase of 0.5407 units in the homework marks.
