Suppose x has a distribution with μ=76 and σ=8. (a) If random samples of size n=16 are selected, can we say anything about the x
ˉ
distribution of sample means? Yes, the x
ˉ
distribution is normal with mean μ x
ˉ
=76 and σ x
ˉ
=2. Yes, the x
ˉ
distribution is normal with mean μ x
ˉ
=76 and σ x
ˉ
=0.5. Yes, the x
ˉ
distribution is normal with mean μ x
ˉ
=76 and σ x
ˉ
=8. No, the sample size is too small.
