Answer

(answers may vary) $X_{\text{min}}=7$, $X_{\text{max}}=36$ $Y_{\text{min}}=9$, $X_{\text{max}}=41$

Work Step by Step

Recall: When creating a scatterplot, the following settings must be followed: $X_{\text{min}}$ should be slightly lower than the lowest $x$-value $X_{\text{max}}$ should be slightly higher than the highest $x$-value $Y_{\text{min}}$ should be slightly lower than the lowest $y$-value $Y_{\text{max}}$ should be slightly higher than the highest $y$-value The given data has the following characteristics: lowest $x$ value is $8$ and maximum is $35$; lowest $y$ value is $10$ and maximum is $40$ Thus, one reasonable sest of $x$-scale and $y$-scale would be: $X_{\text{min}}=7$, $X_{\text{max}}=36$ $Y_{\text{min}}=9$, $X_{\text{max}}=41$
