A random variable is normally distributed with a mean of μ = 3,000 and a standard deviation of σ = 200. Determine the mean and standard error of the sampling distribution of the mean with the following sample sizes: n=25; n=100

A random sample of size n = 100 is obtained from a population with μ = 300 and σ = 50. Which of the following statements best describes the sampling distribution of X̄ in terms of its shape, mean, and standard deviation? The sampling distribution of X̄ is approximately normal with mean equal to 300 and standard deviation equal to 5. The sampling distribution of X̄ is approximately normal with mean equal to 30 and standard deviation equal to 5. The sampling distribution of X̄ is approximately normal with mean equal to 300 and standard deviation equal to 50. The sampling distribution of X̄ is approximately normal with mean equal to 3 and standard deviation equal to 0.5. none of the above

A sample of size n=5 is selected from a population. Under what conditions is the sampling distribution of normal? In this problem, suppose the population mean is 125 and the population standard deviation is 20. What are the expected value and the standard error of sample mean?
