K dogs, 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. OA. Yes: the sample size must be over 30 for the sample means to be normally distributed. OB. No; as long as more than 30 samples are collected, the sample means will be normally distributed. OC. No: the samples are collected randomly, so the sample means will be normally distributed for any sample size. OD. No: the original population is normally distributed, so the sample means will be normally distributed for any sample size.

Question
K Weights of golden retriever dogs are normally distributed. Samples of weights of golden retriever dogs, 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. OA. Yes; the sample size must be over 30 for the sample means to be normally distributed. OB. No; as long as more than 30 samples are collected, the sample means will be normally distributed. OC. No; the samples are collected randomly, so the sample means will be normally distributed for any sample size. OD. No; the original population is normally distributed, so the sample means will be normally distributed for any sample size.
