A) is always normally distributed
B) is normally distributed if the population raw scores are normally distributed
C) is considered normally distributed if N 300

Question

The sampling distribution of the mean _________.
A) is always normally distributed
B) is normally distributed if the population raw scores are normally distributed
C) is considered normally distributed if N > 300
D) is normally distributed if the population raw scores are normally distributed and is considered normally distributed if N > 300

Quizplus · Accepted Answer

The sampling distribution of the mean is normally distributed if the population raw scores are normally distributed, and if the sample size is large enough (typically N > 30 or N > 300, depending on the population distribution). Therefore, choice D is the best answer as it includes both conditions.
