Question

A testing service makes an error that causes all the SAT scores for several thousand students to be low by 58 points. Which statement is true?

Group of answer choices

A) All the scores had the same relative error, but the absolute errors varied. The percentage was the same, but the difference between the measurement and the true value varied.

B) All the scores had the same relative error, but the absolute errors varied. If all of the scores have the same relative error, then they will be the same amount of points less than the actual score.

C) All the scores had the same absolute error, but the relative errors varied. The relative error for any given score will be that score divided by 58.

D) Both the absolute and relative errors were the same in all cases because the same error is made for each score.
