Question

Updated - exactly how it is asked

Suppose x has a distribution with μ = 59 and σ = 8.

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 μ _x = 59 and σ _x = 0.5.Yes, the x distribution is normal with mean μ _x = 59 and σ _x = Yes, the x distribution is normal with mean μ _x = 59 and σ _x = 2.

Find P(55 ≤ x ≤ 60). (Round your answer to four decimal places.)
