Option 1, 2, and 3 are incorrect as the formulas for calculating the sum of squares within rows are not correct. Option 4 is correct as it represents the correct formula for calculating the sum of squares within rows. Option 1 is incorrect as it includes the term (X_p - X_p), which cancels out to 0. Therefore, option 4 can be simplified to: 5 3 _ 3 _ _ F1F1F1S1F1F1F10 F1F1F1S1F1F1F10 X_ip - X)² + F1F1F1S1F1F1F10 X_p - X)² i=1 p=1 p=1 Hence, option 1 and 4 are both correct, and the answer is E.
