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.
