Weights of golden retriever dogs are normally distributed. samples of weights of golden retriever dogs, each of size nequals15, 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; the original population is normally distributed, so the sample means will be normally distributed for any sample size. c. no; the samples are collected randomly, so the sample means will be normally distributed for any sample size. d. no; as long as more than 30 samples are collected, the sample means will be normally distributed.
