4. The population of incomes in a particular community is thought to be highly right-skewed with a mean equal to $49,524 and a standard deviation equal to $6,428. Based on this, if a sample of size n = 64 is selected, the sampling distribution would have a standard deviation equal to the population standard deviation, but the mean of the sampling distribution will be only one-eighth of the population mean. 5. If a population is normally distributed, then the sampling distribution for the sample mean will always be normally distributed only when sample size is at least 30.
