Suppose x has a distribution with μ = 40 and σ = 12. (a) if random samples of size n = 16 are selected, can we say anything about the x distribution of sample means? yes, the x distribution is normal with mean μ x = 40 and σ x = 0.8. yes, the x distribution is normal with mean μ x = 40 and σ x = 12. yes, the x distribution is normal with mean μ x = 40 and σ x = 3. no, the sample size is too small. changed: your submitted answer was incorrect. your current answer has not been submitted. (b) if the original x distribution is normal, can we say anything about the x distribution of random samples of size 16? no, the sample size is too small. yes, the x distribution is normal with mean μ x = 40 and σ x = 3. yes, the x distribution is normal with mean μ x = 40 and σ x = 12. yes, the x distribution is normal with mean μ x = 40 and σ x = 0.8.
