1) Software reports that for the association between marital status and happiness, the $\chi^2$= 236.4.
Estimate the p-value using Table C on Canvas. If $\alpha$ = 0.05, would you reject the null hypothesis that
marital status and happiness are statistically independent? Be sure to pay attention to the degrees of
freedom in this table when estimating the p-value.
