Question 275880: 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 World Almanac Books, 2002.
country’s mathematics score and the number of days spent in school.
(b) Test your conjecture by using a box plot to compare students 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 215 63
Italy 204 64
Jordan 191 40
Korea 222 73
Scotland 191 61
Slovenia 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
