Suppose x has a distribution with μ = 49 and σ = 6. (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 = 49 and σ x = 1.5.No, the sample size is too small.Yes, the x distribution is normal with mean μ x = 49 and σ x = 0.4.Yes, the x distribution is normal with mean μ x = 49 and σ x = 6. (b) If the original x distribution is normal, can we say anything about the x distribution of random samples of size 16? Yes, the x distribution is normal with mean μ x = 49 and σ x = 6.No, the sample size is too small.Yes, the x distribution is normal with mean μ x = 49 and σ x = 0.4.Yes, the x distribution is normal with mean μ x = 49 and σ x = 1.5. Find P(45 ≤x≤ 50). (Round your answer to four decimal places.)
