Suppose (X₁, X₂, ..., X9) is a random sample from Normal(µ = 2,0² = 4²). Let X be the sample mean of X₁, X2,...,. X9 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. Answer the following No. 1 The distribution of X is Normal with mean: Answer: No. 2 and variance: Answer: No. 3 The distribution of Answer: √9 is Normal with mean:
