Transcribed Image Text:Suppose x has a distribution with u = 78 and o = 8.
In USE SALT
(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 u= 78 and o = 2.
Yes, the x distribution is normal with mean u ;= 78 and o = 0.5.
Yes, the x distribution is normal with mean u= 78 and o = 8.
© 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?
Yes, the x distribution is normal with mean u- = 78 and o; = 2.
Yes, the x distribution is normal with mean u- = 78 and o;= 0.5.
O Yes, the x distribution is normal with mean u-- 78 and o= 8.
O No, the sample size is too small.
