Essay

A sports researcher is interested in determining if there is a relationship between the
number of home team and visiting team wins and different sports. A random sample of
526 games is selected and the results are given below. Test the claim that the number of
home team and visiting team wins is independent of the sport. Use $\alpha = 0.01$ $$\begin{array} { l | c c c c } & \text { Football } & \text { Basketball } & \text { Soccer } & \text { Baseball } \\\hline \text { Home team wins } & 39 & 156 & 25 & 83 \\\text { Visiting team wins } & 31 & 98 & 19 & 75\end{array}$$
