Answer 1

For a population with parameters as shown in the image below

(a) Mean of the distribution

(b)Standard deviation of the distribution

`\begin{gathered} \sigma_{\bar{x}\text{ }}\text{ = }\frac{\sigma}{\sqrt[]{n}} \\ \sigma_{\bar{x}\text{ }}\text{ = }\frac{16.7}{\sqrt[]{83}} \\ \sigma_{\bar{x}\text{ }}\text{ = }(16.7)/(9.11) \\ \sigma_{\bar{x}\text{ }}\text{ = 1.833} \\ \sigma_{\bar{x}\text{ }}\text{ = 1.83 (2 d.p)} \end{gathered}`

Hence the value of the mean of the distribution = 245.9 and the standard deviation of the distribution = 1.83
