Question

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 toosmall? Explain Choose the correct answer below. A. Yes: the sample size must be over 30 for the sample means to be normally distributed. O B. No; the original population is normally distributed, so the sample means will be normally distributed for any sample size. O C. No; as long as more than 30 samples are collected, the sample means will be normally distributed. OD. No; the samples are collected randomly, so the sample means will be normally distributed for any sample size. hen seven basketball players are about to have a free-throw competition, they often draw names out of a hat to randomly select the order in which they shoot What is the probability that they shoot free throws in lphabetical order? Assume each player has a different name (shoot free throws in alphabetical order)-5040 Type an integer or a simplified fraction.)

Explanation / Answer

Yes, since the original population is not normally distributed given and sample size is less than 30, we can't conclude that sample mean is normally distributed.
