Question: A sample of eight observations of variables x and y is shown below:

x	5 3 7 9 2 4 6 8
y	20 23 15 11 27 21 17 14

Also, Correlation of x and y = -0.991

I-) Calculate and interpret the coefficient of determinations (Rxy2and Ryx2)= “Rxy squared and Ryx squared”

II-) How is the value of the correlation coefficient yx r affected in each of the following

cases? Please explain your reasoning briefly.

a) Each x value is multiplied by 3.

b) Each x value is switched with the corresponding y value.

c) Each x value is increased by 4.
