The scatterplot below shows the relationship between poverty rate in the 51 states in the US (including DC) and percentage of households with a female head (no husband present). The average poverty rate is 11.35% with a standard deviation of 3.1% and the average percentage of households with a female head is 11.63% with a standard deviation of 2.36%. The correlation between these variables is 0.53. Which of the below is the correct linear model for predicting poverty rate from percentage of households with a female head.

The scatterplot below shows the relationship between poverty rate, y, in the 51 states in the US (including DC) and the high school graduation rate, x. The linear regression equation for predicting poverty is as follows: y = 64.68 - 0.62x The actual high school graduation rate for a certain state is 78.3%, and the actual poverty rate in that state is 17.234%. What is the residual for this observation? (a) Residual = (b) Interpret the meaning of the residual:

Poverty Rates The data (top, right) represent the percentage of families with children in the United States whose income is below the poverty level. (a) With a graphing utility, draw a scatter plot of the data. Comment on the type of relation that appears to exist between the two variables. (b) Decide on a function of best fit to these data (linear, quadratic, or cubic), and use this function to predict the percentage of U.S. families with children that were below the poverty level in $2016(t=13) .$ Compare your prediction to the actual value of 15.0 . (c) Draw the function of best fit on the scatter plot drawn in part (a).

The scatter diagram drawn in MINITAB shows the relation between the percentage of the population of a state plus Washington, DC, that has at least a bachelor's degree and the median income (in dollars) of the state for $2009 .$ Source: U.S. Census Bureau (a) Describe any relation that exists between level of education and median income. (b) One observation appears to stick out from the rest. Which one? This particular observation is for Washington, DC. Can you think of any reasons why Washington, DC, might have a high percentage of residents with a bachelor's degree, but a lower than expected median income? (c) The correlation coefficient between the percentage of the population with a bachelor's degree and median income with Washington, DC, included in the data set is 0.718. The correlation coefficient without Washington, DC. included is $0.802 .$ What property does this illustrate about the linear correlation coefficient?
