Answer 1

To find the total number of students who tested, you need to add the number of tests represented in each bar of the histogram:

- 30 to 40: 1 test
- 40 to 50: 1 test
- 50 to 60: 5 tests
- 60 to 70: 6 tests
- 70 to 80: 8 tests
- 80 to 90: 9 tests
- 90 to 100: 11 tests

Now, we can sum those numbers:

1 + 1 + 5 + 6 + 8 + 9 + 11 = 41

Therefore, the total number of students who tested is **41 students**.
