Florence Nightingale (1820-1910) is mostly known because of her work as a nurse during the Crimean War and her contribution to the reform in sanitary conditions at military hospitals. She is considered the mother of modern nursing and the creator of the first conceptual model of nursing. From a very young age she stood out in mathematics, and later on she applied her knowledge on statistics to epidemiology and to health statistics. She was the first woman to be admitted at the British Royal Statistical Society, and she was an honorary member of the American Statistical Association.

Here is a statistics problem that concerns all citizens.

The following table shows the results of the first statistical study on the amount of urban waste generated annually by each autonomous community in Spain conducted by the Spanish National Institute of Statistics (INE). Read and interpret the data on the table and answer the following questions:

                                                           “El País, July 13th, 2000”

Please answer the following questions:

1. Draw a bar chart and a pie chart to represent the data on the table. Choose which one best illustrates the situation.
2. What are the top three autonomous communities whose inhabitants generate the most waste? What are the three that generate the least?
3. If we wanted to know the amount of waste generated in total in each autonomous community, what information would we need?
4. What is the average kg of waste that each Spanish person generates?
5. If there were 40.57 million Spanish citizens in 2000, what was the approximate amount of urban waste generated in Spain that year?
