8. The following data, with the... The following data, with the corresponding Excel scatterplot, show the average growth rate of Weeping Higan cherry trees planted in Washington, DC. At the time of planting, the trees were one year old and were all six feet in height. 2 3 4 6 7 10 11 Age (vears) 1 Height (feet 6 9.5 13 15 16.5 17.5 18.5 1919.519.719.8 5 Height (in feet) 6.1082In(x)+6.0993 R 0.9863 25 20 15 Height (in feet) 10 6 10 12 Which of the following is the correlation coefficient between Height and In(Age)? 0.9863 0.9863 0.9931 0.9931 Given the coefficient of determination R2 for the regression equation, the coefficient of correlation between y and In(x) is computed asv-VR

Explanation / Answer

Correlation Coefficient = Coefficient of Determination

=R^2

=0.9863

=0.9931

Also, relation is positive as visible in plot, as Age increases, Height also increases.
