40. A graph similar to the following one was depicted on a package of cigarettes in Canada.
a. Make a circle graph of the data.
b Explain which graph you think is more effective.
c. Explain whether you would like to see this labeling on cigarette packages in the United States.
59. In 1991, students from countries around the world took the International Assessment of Educational Progress test. The following table gives the average mathematics scores for 15 countries, along with the number of days that students in each country spend in school each year.
(a) Make a conjecture about the relationship between the countrys' mathematics score and the number of days spent in school.
(b) Test your conjecture by using a box plot to compare sudents who spend 190 days or fewer in school with those who spend more than 190 days in school.
(c) Explain how your graph supports or disproves your conjecture
Country Days of School Math Score
Canada 188 62
France 174 64
Hungary 177 68
Ireland 173 61
Israel 21$ 63
Italy 204 64
Jordan 191 40
Fsorea 222 73
Seotland 191 61
Slovnia 190 57
Soviet Union 198 70
Spain 188 55
Switzerland 207 71
Taiwan 222 73
United States 178 55
(d) Draw a scatterplot for the data and see if there seems to be a correlation between mathematics scores and days in school. Is this the same message your box plot gave you? Which plot would you use to support your conjecture?
60. Use the data in the following table to compare the number of people living in the United States from 1810 through 1900 and the number living in the United States froni 1910 through 2000. Use any form of graphical representation to make the comparison and explain why you chose the representation that you did.
