(a)Develop a crosstabulation for the data, with x as the row variable and y as the column variable. For x use classes of 10-29, 30-49, and so on; for y use classes of 20-39, 40-59, and so on.

	y	Grand Total
20-39	40-59	60-79	80-99
x	10-29
30-49
50-69
70-90
Grand Total

(b)Compute the row percentages. (Round your answers to one decimal place.)

	y	Grand Total
20-39	40-59	60-79	80-99
x	10-29
30-49
