How do you determine with suitable hypothesis testing whether age and sex are associated, using the data provided (my guess is it is a chi squared test)? State your hypotheses. If there is evidence for some association between age and sex, identify the particular combinations that are contributing to this conclusion (which combinations contribute to a high test statistic?).
