5 Task 3k. Below is a crosstab with region2 as the column variable and beltfrnt as the row variable. The cells for the crosstabs report the frequency of responses that fall into a cell and the column percent. The Chi-square statistic for this table is also reported. belfrnt Seat Belt Law--Front seat only * region2 Crosstabulation belfrnt Seat Belt Law--Front seat only Total 0 o 1 Yes region2 1 orth 2 Midwest 3 South 4 West Total % 8.3% 17.6% 69.2% 35.3% % 91.7% 82.4% 30.8% 64.7% % 100.0% 100.0% 100.0% 100.0% Pearson Chi-Square Likelihood Ratio Linear-by-Linear Association of Valid Cases Chi-Square Tests Asymp.
