Final Answer :
D
Explanation :
The SAT score associated with a z-score of -2.0 is approximately 200, so choice D is correct.
Choice A is also correct, as a T-score of 30 is associated with a z-score of -2.0.
Choice B is correct, as a DIQ of 70 is associated with a z-score of -2.0.
Choice C is correct, as a percentile of 2 is associated with a z-score of -2.0.
Choice E is incorrect, as a stanine of 1 is associated with a range of z-scores from approximately -3.0 to -2.25, so a z-score of -2.0 would fall within this range and correspond to a stanine of 1.
Choice A is also correct, as a T-score of 30 is associated with a z-score of -2.0.
Choice B is correct, as a DIQ of 70 is associated with a z-score of -2.0.
Choice C is correct, as a percentile of 2 is associated with a z-score of -2.0.
Choice E is incorrect, as a stanine of 1 is associated with a range of z-scores from approximately -3.0 to -2.25, so a z-score of -2.0 would fall within this range and correspond to a stanine of 1.
