Answer the following questions. Remember that there is only one right answer for each item.

1. The population in the city of Springfield, Missouri, in March, 2014, was 200,000.
   The number of new cases of HIV was 28 between January 1 and June 30, 2014.
   The number of current HIV cases was 130 between January 1 and June 30, 2014.
   – The incidence rate of HIV cases for this 6-month period was
2. The prevalence rate of HIV cases in Springfield, Missouri, as of June 30, 2014, was
3. In a North African country with a population of 5 million people, 50,000 deaths occurred during 2014. These deaths included 5,000 people from malaria out of 10,000 persons who had malaria.
   What was the total annual mortality rate for 2014 for this country? (Please show your work.)
4. What was the cause-specific mortality rate from malaria? (Please show your work.)
   Cause-specific mortality rate: (# of deaths per a specific disease)/midyear population) X 1000
5. What was the case-fatality percentage from malaria?
   Case-fatality percentage: (# of persons dying from a disease after diagnosis or set period/ # of persons with the disease) X 100
6. Fill in and total the 4 X 4 table for the following disease parameters:
   • Total number of people with lung cancer in a given population = 120
   • Total number of people with lung cancer who smoked = 90
   • Total number of people with lung cancer who did not smoke = 30
   • Total number of people who smoked = 150
   • Total number of people in the population = 350
7. From Question 6, what is the total number of people with no lung cancer?
8. From question 6, what is the total number of people who smoked but did not have lung cancer?
9. Set up the problem for relative risk based on the table in #6.
10. Calculate the relative risk.
