Essay

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