\begin{enumerate}
	\item A box and whisker plot for a data set is shown in figure \ref{boxplot}.
	\begin{enumerate}
		\item Compute the corresponding five point summary
		\item Find the inter-quartile range

	\item Given the data set $\{7,  8, 10, 13,  6, 13, 13, 11, 10,  5,  6\}$,
	\begin{enumerate}
		\item Compute the corresponding five point summary
		\item Find the inter-quartile range
		\item Draw the corresponding box-plot
	\end{enumerate}
	
	\item Classify the histograms shown in figure \ref{hists} as symmetric, skewed, unimodal or bimodal. Which one is approximately normal?
