Kara Macias · Answer 1

A.) r = - 0.3669

B.) r = - 0.3669

C.) there is no change in the value of r

Step-by-step explanation:

Row 1 : 20, 21, 37, 48, 56, 63, 72

Row 2: 177, 158, 164, 171, 129, 186, 134

A.) Taking Row 1 values as X. And row 2 values as Y.

Regression equation using the correlation Coefficient calculator:

r = - 0.3669

B) Taking Row 1 values as Y. And row 2 values as Y.

Regression equation using the correlation Coefficient calculator:

r = - 0.3669

C.) the correlation does not change.
