The appropriate two-way frequency table for the time will like the following:

               

                              RAP      ROCK     COUNTRY     TOTAL

Grades 9-10           40           30            55                  125

Grades 11-12         60           25            35                  120

TOTAL                    100          55            90                  245

The sum of the column total and the row total is equal.

125 + 120 = 100 + 55 + 90

245 = 245
