Enter the total number of people Ellen surveyed.

Answer 1

To find the total number of people Ellen surveyed, we need to count the number of data entries in the table.

The data shows the number of hours of sleep for each entry:

- 7
- 8
- 9
- 8
- 7
- 9
- 8
- 7
- 9
- 10
- 9

Counting these entries gives us a total of 11 entries.

Thus, the total number of people Ellen surveyed is **11**.
