Question
Suppose x has a distribution with=74and=8. (a) If random samples of size n = 16 are selected, can we say anything about the x distribution
Supposexhas a distribution with=74and=8.
(a)
If random samples of sizen= 16 are selected, can we say anything about thexdistribution of sample means?
Yes, thexdistribution is normal with meanx= 74 andx= 2.
Yes, thexdistribution is normal with meanx= 74 andx= 0.5.
Yes, thexdistribution is normal with meanx= 74 andx= 8.
No, the sample size is too small.
(b)
If the originalxdistribution isnormal, can we say anything about thexdistribution of random samples of size 16?
Yes, thexdistribution is normal with meanx= 74 andx= 2.
Yes, thexdistribution is normal with meanx= 74 andx= 0.5.
Yes, thexdistribution is normal with meanx= 74 andx= 8.
No, the sample size is too small.
