2. Suppose (X₁, X₂, ..., X9) is a random sample from Normal(u = 2,0² = 4²). Let X be the sample mean of X₁, X₂, ..., X, and S2 be the sample variance of X₁, X₂,..., X9. For items asking for the distribution of a statistic, do not forget to specify the parameters. a. Find P(X1-21). 4 b. Find P(|X₁-2|< 1). (Hint: Recall that Ix| ≤ a means that -a ≤x≤a.) c. Find P(|X-2|< 1).
