Commercial dredging operations in ancient rivers occasionally uncover archaeological artifacts of great importance. One such artifact is Bronze Age spearheads recovered from ancient rivers in Ireland. A recent study gave the following information regarding discoveries of ancient bronze spearheads in Irish rivers.

(a) Make a Pareto chart for these data.

(b) Make a circle graph for these data.

River           Bann    Blackwater      Erne    Shannon      Barrow

No of             19          8                     15             33             14

spearheads

This is the supporting data from online source.

1. the chart , the vertical side is the number of spearheads, and the horizontal side is the river. the rivers are drawn in boxes against the vertical numbers

2. the pie chart is constructed in angles.

19/79*360=[tex]86.5^{0}[/tex]

8/79*360=36.45[tex]^{0}[/tex]

15/79*360=[tex]68.35^{0}[/tex]

33/79*360=[tex]150.37^{0}[/tex]

14/79*360=[tex]63.79^{0}[/tex]
