8. Archaeology: Ireland 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. River Bann Shannon Barrow Blackwater Erne 15 8 33 14 No. of spearheads 19 (Based on information from Crossing the Rubicon, Bronze Age Studies 5, Lorraine Bourke, Department of Archaeology, National University of Ireland, Galway.) (a) Make a Pareto chart for these data. (b) Make a circle graph for these data.

5. Education: Does College Pay Off? It is costly in both time and money to go to college. Does it pay off? According to the Bureau of the Census, the an- swer is yes. The average annual income (in thousands of dollars) of a house- hold headed by a person with the stated education level is as follows: 24.3 if ninth grade is the highest level achieved, 41.4 for high school graduates, 59.7 for those holding associate degrees, 82.7 for those with bachelor's degrees, 100.8 for those with master's degrees, and 121.6 for those with doctoral de- grees. Make a bar graph showing household income for each education level. 6. Interpretation Consider the two graphs depicting the influence of advertise- ments on making large purchases for two different age groups, those 18 to 34 years old and those 45 to 54 years old (based on a Harris Poll of about 2500 adults aged 18 or older). Note: Other responses such as "not sure" and "not applicable" were also possible. Influence of Advertising on Most Recent Large Purchase 45% 44% 18-34 years old Influential Not influential 80% 60% 40% 20% 0% 45-54 years old Influential Not influential (a) Taking a quick glance at the graphs, Jenna thought that there was very little difference (maybe less than 1%) in the percentage of the two age groups who said that ads were influential. How would you change the graphs so that Jenna would not be misled so easily? Hint: Look at the vertical scales of the two graphs. (b) Take the information from the two graphs and make a cluster bar graph showing the percentage by age group reporting to be influenced by ads and those reporting they were not influenced by ads. 7. Commercial Fishing: Gulf of Alaska It's not an easy life, but it's a good life! Suppose you decide to take the summer off and sign on as a deck hand for a commercial fishing boat in Alaska that specializes in deepwater fishing for groundfish. What kind of fish can you expect to catch? One way to answer this question is to examine government reports on groundfish caught in the Gulf of Alaska. The following list indicates the types of fish caught annually in thousands of metric tons (Source: Report on the Status of U.S. Living Marine Resources, National Oceanic and Atmospheric Administration): flatfish, 36.3; Pacific cod, 68.6; sablefish, 16.0; walleye pollock, 71.2; rockfish, 18.9. Make a Pareto chart showing the annual harvest for commercial fishing in the Gulf of Alaska. 8.
