What is a scatterplot that shows how life expectancy responds to changes in poverty level percentile rank with the correct statement that describes the overall pattern of the data?
Do poorer people tend to have shorter lives than richer people? Two researchers ranked all counties in the United States by their poverty level and then divided them into 2020 groups, each representing approximately 5%5% of the overall U.S. population. The bottom 5%5% were the least impoverished (wealthiest) and top 5%5% (the 100th100th percentile) the most impoverished. Life expectancies at birth for each of the 2020 groups were calculated based on life tables. The table contains the data for poverty percentiles (with higher percentiles corresponding to greater poverty) and life expectancies at birth (in years) in 2010 for males in the 20 groups.20 groups.
