The population of current statistics students has ages with mean and standard deviation . Samples of statistics students are randomly selected so that there are exactly 48 students in each sample. For eachsample, the mean age is computed. What does the central limit theorem tell us about the distribution of those meanages?

Choose the correct answer below.

A.

Because n>30, the sampling distribution of the mean ages can be approximated by a normal distribution with mean and standard deviation

48.

B.

Because n>30, the sampling distribution of the mean ages is precisely a normal distribution with mean and standard deviation

48.

C.

Because n>30, the sampling distribution of the mean ages can be approximated by a normal distribution with mean and standard deviation .

D.

Because n>30, the central limit theorem does not apply in this situation.
