Question
Weights of golden retriever dogs are normally distributed. Samples of weights of golden retriever dogs, each of sizen = 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.
A. Yes; the sample size must be over 30 for the sample means to be normally distributed.
B. No; as long as more than 30 samples are collected, the sample means will be normally distributed.
C. No; the original population is normally distributed, so the sample means will be normally distributed for any sample size.
D. No; the samples are collected randomly, so the sample means will be normally distributed for any sample size.
