Use a X² test to test the claim that in the given contingency table, the row variable and the column variable are independent.
-The table below shows the age and favorite type of music of 668 randomly selected people. $$\begin{array} { l | r r r }
& \text { Rock } & \text { Pop } & \text { Classical } \
\hline 15 - 25 & 50 & 85 & 73 \
25 - 35 & 68 & 91 & 60 \
35 - 45 & 90 & 74 & 77
\end{array}$$
Use a 5 percent level of significance to test the null hypothesis that age and preferred music type are independent.
