[Q No. 51-60] Let [katex] X_1,X_2,\dots,X_9 [/katex] be a random sample from a [katex] N(\mu,\sigma^2) [/katex] distribution, where [katex] \mu \in \mathbb{R} \text{ and } \sigma>0 [/katex] are unknown. Let the observed values of [katex] \bar{X} = \frac{1}{9} \sum_{i=1}^9 \text{and} S^2 = \frac{1}{8} \sum_{i=1}^{9} ( X_i -\bar{X} )^2 [/katex] be 9.8 and 1.44, respectively. If…
