Poverty thresholds are determined by the U.S. Census Bureau. A poverty threshold represents the minimum annual household income for a family not to be considered poor. In 2004, the poverty threshold for a familyof four with two children under the age of 18 years was $19,157. In 2014, the poverty threshold for a family of four with two children under the age of 18 years was $24,008. Assuming poverty thresholds increase in a straight-line fashion, use the midpoint formula to estimate the povertythreshold of a family of four with two children under the age of 18 in 2009. How does your result compare to the actual poverty threshold in 2009 of $21,756?

The toco toucan, the largest member of the toucan family, possesses the largest beak relative to body size of all birds. This exaggerated feature has received various interpretations, such as being a refined adaptation for feeding. However, the large surface area may also be an important mechanism for radiating heat (and hence cooling the bird) as outdoor temperature increases. Here are data for beak heat loss, as a percent of total body heat loss from all sources, at various temperatures in degrees Celsius.

However, the large surface area may also be an important mechanism for radiating heat (and hence cooling the bird) as outdoor temperature increases. The table contains data for beak heat loss, as a percentage of total body heat loss from all sources, at various temperatures in degrees Celsius.

Convinced about the importance of data processing through of statistics, Matheus, a production engineer, needs to do an analysis of the following data, which refers to daily production, in tons, from a company that operates in the processing industry of sugar cane. b) In addition to organizing the data in the frequency distribution, it is important to interpret the data. So Matheus performs the interpretation of the following data. - The interpretation of the absolute frequency of the third class. - The interpretation of the relative frequency of the second class. - The interpretation of the accumulated absolute frequency of the fourth class. What is the correct interpretation performed by Matheus for the previous questions?

Turbid water is muddy or cloudy water. Sunlight is necessary for most life forms; thus turbid water is considered a threat to wetland ecosystems. Passive filtration systems are commonly used to reduce turbidity in wetlands. Suspended solids are measured in mg/l. Is there a relation between input and output turbidity for a passive filtration system and, if so, is it statistically significant? At a wetlands environment in Illinois, the inlet and outlet turbidity of a passive filtration system have been measured. A random sample of measurements are shown below.
