5.   A class recently conducted a river study to determine whether there is a relationship between downstream distance and particle shape.  They calculated the Cailleux Index (degree of roundness) for a sample of 40 pebbles at one site. The results are shown in the following table.

Table 4: Cailleux Roundness Index

a.   Draw a histogram showing the above data. Note: The graph must be hand drawn on graph paper, scanned and inserted into the assignment and uploaded as a.pdf doc. Do not use Excel to plot the graph. Show working                                                                                              (7 marks)
