5. A student states that a decrease in the percent of 18-64 yr-olds with no high school diploma will no doubt lead to a decrease in the percent of low-income working families.

The student, therefore, believes that it is the responsibility of these sub-groups of the population and their advocates to address the working poor issue themselves. Use the key rules about samples and extrapolation when making inferences from correlations to write a socially responsible and statistically appropriate response regarding the validity of the student's beliefs.
