Statistics

Many construction sites post a sign that proclaims the number of days since the last accident that injured an employee.

(a) A friend who walks by the construction site tells you to expect to see an ambulance any day. The count has grown from 20 days to 60 days to 100 days. An accident is coming any day now. Do you agree?

(b) Would you feel safer visiting a work site that proclaimed it had been 100 days since the last accident, or one that showed that the last accident was 14 days ago?
