🔎 Safety Data Detectives

A fictional school study compares two groups. Each group had 100 bicycle accidents. These numbers are invented for our classroom activity; they are not real research results.

Group	Head injuries
Without helmets	30
With helmets	10

1. How many fewer head injuries were recorded in the helmet group?2. What percentage fewer injuries were recorded compared with the no-helmet group? (Round to 1 decimal place.)3. Does this data prove that helmets prevent every injury? Explain your reasoning.

Think carefully: comparing numbers does not mean every other factor was the same.
