Page 4 of 16 200M+ 4 Ch16 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. 5 Height (feet6 9.5 131516.5 17.5 18.5 19 19.5 19.7 19.8 ars 1 4 Height (in feet) 25 6.1082n(x)+6.0993 R2 0.9863 20 15 Height (in feet) 10 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

Explanation / Answer

Given regression model is

y=6.0993+6.1082 ln(x)

and R square=0.9863

Now correlation coefficient =r=sqrt(R square) =0.9931
