Question

Weights of adult human brains are normally distributed. Samples of weights of adult human brains, each of size n=15, are randomly collected and the sample means are found. Is it correct

to conclude that the sample means cannot be treated as being from a normal distribution because the sample size is too small? Explain. Choose the correct answer below. GEFED OA. It is correct. The sample means cannot be treated as being from a normal distribution because the sample size is n> 30. O B. It is not correct. The sample means can be treated as being from a normal distribution because n <30. O C. It is not correct. The sample means can be treated as being from a normal distribution because the sample weights come from a population that is normally distributed OD. It is not correct. The sample means can be treated as being from a normal distribution because the distribution of the sample means is always normal, regardless of the population or n.
