Perform a chi-square independence test using the critical value approach, provided the conditions for using the test aremet. Be sure to state the hypotheses and the significance level, to obtain the expected frequencies, to obtain the criticalvalue, to compute the value of the test statistic, and to state your conclusion.
-The table below shows the age and favorite type of music of 668 randomly selected people.
$\begin{array} { l | r c c } & \text { Rock } & \text { Jazz } & \text { Classical } \ \hline 15 - 25 & 50 & 85 & 73 \ 25 - 35 & 68 & 91 & 60 \ 35 - 45 & 90 & 74 & 77 \end{array}$
At the 0.05 significance level, do the data provide sufficient evidence to conclude that an association exists between age and preferred music type?
