Quizplus · Accepted Answer

According to the central limit theorem, regardless of the shape of the raw score distribution, as long as the sample size is sufficiently large (N = 42 is generally considered large enough) the sampling distribution of the mean will approach a normal distribution. Therefore, the answer is B) normally distributed.
