Each possible sample should have - ANSWERthe same probability of being selected Which of the following statements regarding the sampling distribution of sample means is incorrect? - ANSWERThe standard deviation of the sampling distribution is the standard deviation of the population. A simple random sample of size n from an infinite population is a sample selected such that - ANSWEReach element is selected independently and is selected from the same population The fact that the sampling distribution of sample means can be approximated by a normal probability distribution whenever the sample size becomes large is based on the - ANSWERcentral limit theorem.
