[Solution] Suppose that x has a distribution with μ =25 and σ =8 if random samples of size n=16 are selected, can we say anything about the xbar
Question: Suppose that x has a distribution with \(\mu \) =25 and \(\sigma \) =8
- if random samples of size n=16 are selected, can we say anything about the xbar distribution of samples mean?
- If the original x distribution is normal, can we say anything about the xbar distribution of random samples of size 16? Find P(68≤ xbar ≤ 73).
