A sample of n = 5 scores has a mean of M = 12.What is ΣX for this sample? A)12/5 = 2.40 B)5/12 = 0.417 C)5(12) = 60 D)5²=25

Question

Quizplus · Accepted Answer

ΣX for a sample is the sum of all the scores in the sample. As given, the sample size is n=5 and the mean is M=12. Therefore, the sum of all the scores in the sample can be calculated as ΣX = n*M = 5*12 = 60. Hence, option C is the correct answer. The other options are incorrect. Option A calculates the average of the scores in the sample, option B calculates the reciprocal of the sample mean, and option D is an incorrect equation that does not apply here.
