In the file "CriminalConvictions.csv" are data on whether adolescent boys went on to develop criminal records and the level of income that their families maintained as they grew up. Perform tests that assess which pairs of income categories significantly differ in the proportion of boys who went on to develop criminal records and use Holm's correction to account for the fact that you are engaging in multiple testing. Please indicate which of the pairwise comparisons listed below are statistically significant.
