Develop a crosstabulation for the data, with @ as the row variable and y as the column variable. For a use classes of 10 - 29, 30 - 49, and so on; for y use classes of 20 - 39, 40 - 59, and so on. y 20 - 39 40 - 59 60 - 79 80 - 100 Grand Total X X 10 - 29 X 30 - 49 X 50 - 69 X X X X 70 - 90 Grand Total X X X X Xb.
