Draw or imagine a smooth curve through the tops of the bars on the histogram.  Describe its shape (for examples, does it go straight across, look like a bell curve, or have another general shape?) About 68% of the data values lie between what two data values?  About 95% of the data values lie between what two data values? Why would the answers to these questions be valuable for someone to interpreting this data?
