### Part Two

Use the following data in part two:

As of Sunday, 11 May 2003, a cumulative total of 7296 cases of Severe Acute Respiratory Syndrome (SARS) with 526 deaths have been reported from 30 countries. This represents an increase of 2857 new cases and 263 deaths since 24 April 2003. 3087 people have recovered. - Data from the World Health Organization

2. _______ There are roughly 177 nations on the planet. 30 is what percent of 177?
3. _______ Pneumonia has a 5% fatality (death) rate. What is 5% of 7296?
(this is the number who would have been expected to die if they had contracted pneumonia)
4. _______ Flu has a fatality rate of 3.2%. What is 3.2% of 7296?
5. _______ The Federated States of Micronesia has a population of 110,000 people. If everyone in the FSM contracted SARS what number would be expected to die?
6. _______ What is the percent increase from 263 deaths to 526 deaths?
7. _______ If tomorrow the World Health Organization reports an increase of 10% in the number of cases worldwide, what will be the total number of cases globally?
8. _______ Using the number of cases and the number who have recovered, determine the number of people who presently have SARS and have not yet recovered.
9. _______ There exists data that suggests the actual SARS death rate is closer to 20%. What is 20% of the number of people who have SARS now (your answer to the question above.)
