In May 2008, in response to an outbreak of TB in her city, public health nurse Jenny Myers was called on to direct screening in two schools. Andrews Elementary School had 400 students during the screening, and 10 students tested positive.
At Blackwell High School, 30 of 1200 students tested positive. Following analysis, Jenny determined that the TB prevalence rates were:
1. About the same at both schools.
2. Higher at Blackwell than at Andrews.
3. Higher at Andrews than at Blackwell.
4. Impossible to determine due to the small population size.

During 2006 in Woodland County, there were 175 cases of syphilis reported to the health department. In July 2006, there were approximately 250,000 residents of Woodland County. Thus the incidence of syphilis for 2006 was
1. 7 per 1000.
2. 7 per 100,000.
3. 70 per 100,000.
4. 700 per 100,000.
