4. [-/0.22 Points] DETAILS BBUNDERSTAT12 6.5.008.MI.S. MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER Suppose x has a distribution with it = 88 and o = 8. LO USE 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 u - = 88 and o - = 2. Yes, the x distribution is normal with mean u - = 88 and o = = 0.5. Yes, the x distribution is normal with mean it - = 88 and o - = 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 u - = 88 and o - = 2. O Yes, the x distribution is normal with mean u = 88 and o = = 0.5. Yes, the x distribution is normal with mean u - = 88 and o - = 8. O No, the sample size is too small. Find P(84 s x's 89). (Round your answer to four decimal places.)
