Final answer:
The SS for a population given N = 6 scores, ΣX = 12, and ΣX2 = 54 is calculated as 54 - (12²)/6, which equals 30. However, this result is not an option provided in the question, indicating a possible error.
The correct option is not given.
Step-by-step explanation:
The question asks us to find the value of SS (Sum of Squares) for a population given N = 6 scores, where ΣX = 12 and ΣX2 = 54.
The formula for SS in a population is SS = ΣX2 - (ΣX)2/N. So, SS = 54 - (12)2/6 = 54 - 144/6 = 54 - 24 = 30. This value does not match any of the options provided, so the question may contain an error or require re-evaluation.
The correct option is not given.
