The contingency table shows a higher proportion of males (66.67%) exceeding the speed limit compared to females (39.58%). The chi-square test for independence also yields a p-value of 0.002, which is less than the typical significance level of 0.05. This means that there is evidence to suggest that gender and speeding are related. Therefore, we can conclude that gender and speeding are related.
