1. In 2010, a US. Census Bureau report revealed that approximately 14.3% of all Americans were living below the poverty line in 2009. This figure is higher than in 2000, when the poverty rate was 12.2%. Individuals and families living below the poverty line face many obstacles, the least of which is access to health care. In many cases, those living below the poverty line are without any form of health insurance. Using data from the US. Census Bureau, analyze the relationship between living below the poverty line and access to health care for a random sample of 12 states. (The health insurance data are preiAffordable Care Act implementation.)

Census Bureau, The 2012 Statistical Abstract, 2011, Tables 709 and 156. a. Calculate the regression equation (a.k.a. line equation) with percentage of the population without health insurance as the dependent variable, and draw the regression line on the scatterplot. What is its slope? What is the intercept? Are there any states that fall far from the regression line? Which one(s)? 2. Here the relationship between education and television watching is given as a scatterplot, with a line of best fit used to predict viewing habits based on education: 25 R2 Linear = 0.031 20 O O 15 Hours per day watching TV O O 10 O 5 00090000000 0009000 000 0090000 0 0 0009000 0 y = 5.3-0.17x O O O 10 15 20 Highest year of school completed a. What is the independent variable? What is the dependent variable? Why? b. In the regression equation on the scatterplot, what is the y-intercept? Interpret what the y- intercept means in terms of peoples education and tv watching. c. In the regression equation on the scatterplot, what is the slope? Interpret what the slope means in terms of peoples education and tv watching. d. Assume that someone's highest year of school completed was 12. What is their hours per day watching television predicted to be? e. The r-squared of the correlation is given as 0.031. What does that mean
