Essay

Suppose that 10 observations are drawn from a normal population whose variance is 64. The observations are: $\begin{array}{|l|l|l|l|l|l|l|l|l|l|}\hline 13&21&15&19&35&24&14&18&27&30 \\\hline\end{array}$ Test at the 10% level of significance to determine whether there is enough evidence to conclude that the population mean is greater than 20.
