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.
