Question

lhe population or current statistics students has ages with mean and standard deviation ?. samples ot statistics students are randomly selected so that there are exactly 50 students in each sample. For each sample, the mean age is computed. What does the central limit theorem tell us about the distribution of those mean ages? 1) Because n 30, the sampling distribution of the mean ages can be approximated by a normal distribution with mean and standard deviation 2) Because n >30, the sampling distribution of the mean ages can be approximated by a normal distribution with mean ,si and standard deviation ?i 3) Because n >30, the sampling distribution of the mean ages is precisely a normal distribution with mean Ali and standard deviation ?i-
