What is the r^2 value of the following data to three decimal

0.783

Step-by-step explanation:

To find first r and then r square for the data

n statistics, the coefficient of determination, denoted R2 or r2 and pronounced "R squared", is the proportion of the variance in the dependent variable that is predictable from the independent variable(s).

correlation coefficient of x and y = Cov (x,y)/std dev x * std dev Y

Cov (x,y) = E(xy) -E(x)E(y)

Hence calculations would be as follows:

xyxy

122

21020

Mean51284.6

CovE(xy)-E(x)E(y)  24.6

r0.884640297

r^20.782588454

so answre is 0.783 after rounding off.
