\hline & { \text { Brand of Carpet } } \
\hline \text { Family Income } & \text { Brand } \mathrm { A } & \text { Brand B } & \text { Brand C } \

\hline \text { Middle income } & 80 & 68 & 104 \
\hline \text { Low income } & 25 & 35 & 59 \

\end{array}$$ At the 5% level of significance, can you conclude that the brand of carpet purchased is related to the purchaser's family income?
