The Table Shows the Weights (In Pounds) and Monthly Incomes

Essay

The table shows the weights (in pounds) and monthly incomes (in dollars) of nine randomly selected women
between the ages of 18 and 65. Assume that the x-values are the weights and the y-values are the monthly
incomes.
Are the x $$\begin{array} { | l | c | c | c | c | c | c | c | c | c } \hline \text { Weight (lb) } & 113 & 132 & 155 & 122 & 166 & 140 & 118 & 129 & 185 \\\hline \text { Monthly Income (dollars) } & 1420 & 3650 & 5475 & 2310 & 4710 & 2910 & 1720 & 2460 & 4115 \\\hline\end{array}$$ -values matched with the corresponding y-values? That is, is each x-value associated with the
corresponding y-value in some meaningful way? If the x- and y-values are matched, does it make sense to use
the difference between each x-value and the y-value that is in the same column? Why or why not?
