B)Skewed left
C)Normal
D)Binomial

Question

Quizplus · Accepted Answer

When comparing the difference between two independent population means, we use the Central Limit Theorem to assume that the sampling distribution of each population mean will be approximately normal, regardless of the distribution of the original populations. Therefore, the correct answer is C) Normal. Skewed distributions would not be appropriate for this type of comparison, and binomial distributions are not directly related to population means.
