To determine the total number of students who participated in the survey, we need to sum up the totals given at the bottom and right side of the table.
From the table, we notice the following totals for each time preference:
- The total number of students who prefer to have gym class in the morning is 45.
- The total number of students who prefer to have gym class in the afternoon is 55.
These are the overall totals for each column and are summed up in the "total" column at the bottom right of the table:
- Total number of students who participated in the survey is 100.
Thus, the total number of students who participated in the survey is 100.
