Suppose x has a distribution with μ = 76 and a = 8. LUSE SALT (a) If random samples of size n = 16 are selected, can we say anything about the x distribution of sample means? O Yes, the x distribution is normal with mean μ = 76 and a = 76 and σ = 2. = 0.5. O Yes, the x distribution is normal with mean O Yes, the x distribution is normal with mean μ = 76 and x = 8. O No, the sample size is too small. (b) If the original x distribution is normal, can we say anything about the x distribution of random samples of size 16? O Yes, the x distribution is normal with mean = 76 and σx = 2. Yes, the x distribution is normal with mean = 76 and a = 0.5. Yes, the x distribution is normal with mean μ = 76 and x = 8. No, the sample size is too small. Find P(72 ≤ x ≤ 77). (Round your answer to four decimal places.)
