Correct answer: A. 24 divided by 12,000, multiplied by 100,000
- A. 24 divided by 12,000, multiplied by 100,000
- B. 12,000 divided by 24, multiplied by 100,000
- C. 24 divided by total population, multiplied by 1,000
- D. 12,000 divided by total population, multiplied by 1,000

About Epidemiology and Biostatistics
Epidemiology examines the distribution and causes of disease by person, place and time, using measures such as incidence, prevalence, mortality and case-fatality rates. Biostatistics covers data presentation, sampling, averages, variability, probability and interpretation of study results, while distinguishing association from causation.
