Poverty in a Study of How the Burden of Poverty

question 12

Essay

Poverty In a study of how the burden of poverty varies among U.S. regions, a random sample of 1000 individuals from each region of the United States recently yielded the information on poverty (based on defining the poverty level as an income below $10,400 for a family of 4 people). The data are provided in the table below. (All the conditions are satisfied - don't worry about checking them.)
$\begin{array}{|l|c|c|c|c|c|}\hline& \text { Northwest } & \text { Midwest } & \text { South } & \text { West } & \text { Total } \\\hline \text { Poor } & 112 & 105 & 154 & 113 & 484 \\& (121) & (121) & (121) & (121) & \\\hline \text { Not Poor } & \begin{array}{c}888 \\(879)\end{array} & \begin{array}{c}895 \\(879)\end{array} & \begin{array}{c}846 \\(879)\end{array} & \begin{array}{c}887 \\(879)\end{array} & 3516 \\\hline \text { Total } & 1000 & 1000 & 1000 & 1000 & 4000 \\\hline\end{array}$

$\begin{array}{r}\chi^{2}=\quad 0.67+2.12+9.00+0.53+ \\0.09+0.29+1.24+0.07+ \\=14.01\end{array}$
