Using your favorite statistics software package, you generate a scatter plot with a regression equation and correlation coefficient. The regression equation is reported as \[ y = -51.77x + 40.56 \]and the correlation coefficient \( r = -0.9 \).What percentage of the variation in \( y \) can be explained by the variation in the values of \( x \)?\[ r^2 = \_\_\_\_ \] % (Report exact answer, and do not enter the % sign)[Submit Question]**Explanation:**In this problem, you're asked to find the coefficient of determination (\( r^2 \)), which tells you what percentage of the variation in the dependent variable \( y \) is explained by the independent variable \( x \). Given that the correlation coefficient \( (r) \) is \(-0.9\), calculate \( r^2 \) as follows:\[ r^2 = (-0.9)^2 = 0.81 \]Thus, 81% of the variation in \( y \) is explained by the variation in \( x \). Enter the value of \( r^2 \) in the provided space without the percentage sign, as instructed.
