Kaya Reinke & Test:Final Exam -Chapters 11, 12,14 This Question: 1 pt The ooelicient of determination of a set of data points is 0,712 and the slope of the regression line is-3.31.Damine the linear comelation cooficient of the dt What is the linear comelation ooefficient Round to thee decimal places as needed) Enter your anwer in the answer box 5 6 8

Answer 1

We know that coefficient of determination is R² and correlation coefficient is R.

So correlation coefficient is basically the square root of coeficient of determination.

$R=\pm \sqrt{R^2}=\pm\sqrt{0.712}= \pm0.8438\approx -0.844$

Note: The correlation coefficient is negative because the slope is negative
