Consider a large population with a mean of 150 and a standard deviation of 27. A random sample of size 36 is taken from this population. Which of these values is equal to the standard error of the sampling distribution of sample mean? Samples of size 25 are selected from a population with mean 40 and standard deviation 2. The mean of the sampling distribution of sample means is Given a population variance of 0'2 = 36 and a sample size of n = 9. What is the standard deviation of the sampling distribution of a sample mean X
