**Graph Analysis of Norovirus Outbreak Among Students**

The graph illustrates the number of students who became ill with norovirus over a period of two and a half days following a banquet dinner attended by all the field trip students. The horizontal axis represents time in hours, ranging from 0 to 60 hours, while the vertical axis indicates the number of students who fell ill.

**Graph Details:**

- **0 to 8 Hours:** Minimal cases, with 1 student becoming ill.
- **8 to 12 Hours:** The number increases to 3 students.
- **12 to 16 Hours:** A noticeable rise, with 5 students becoming ill.
- **16 to 20 Hours:** The peak time for illness onset, with 12 students affected.
- **20 to 24 Hours:** A slight decrease, as 10 students report illness.
- **24 to 32 Hours:** The number declines further to 6 students.
- **32 to 48 Hours:** Sporadic cases, with numbers dropping to 2 and then 0 students.
- **48 to 60 Hours:** Isolated cases, with 1 student reported.

**Interpretation:**

The graph highlights the incubation period of the virus, showing a sharp increase in cases around 16 to 20 hours after exposure, which peaks and then gradually declines. This data is essential for understanding the virus's spread and implementing preventive measures.
