F1F1F1S1 represents the frequency distribution for the data set: 2, 5, 6, 7, 9, 10, 10, 12 F1F1F1 represents the frequencies of each value: F1 = 1 (there is one 2) F1 = 1 (there is one 5) F1 = 1 (there is one 6) S1 = 1 (there is one 7) F1 = 1 (there is one 9) F1 = 2 (there are two 10s) S1 = 1 (there is one 12) The product of F1F1F1S1XS1UPSP is equal to: 1*1*1*1*1*2*1*10*12*1*1*1*0 = 0 Therefore, the sum F1F1F1S1F1F1F10X² is equal to: 1 + 1 + 1 + 1 + 1 + 2 + 1 + 10 + 12 + 1 + 1 + 1 + 0 = 31 This means the final answer is (31)^2 = 961. However, the question asks for F1F1F1S1F1F1F10X², which is equal to 31. Therefore, the answer is C) 539.
