In a study of

319 comma 043319,043

cell phone users, it was found that

6464

developed cancer of the brain or nervous system. Assuming that cell phones have no effect, there is a

0.0002370.000237

probability of a person developing cancer of the brain or nervous system. We therefore expect about

7676

cases of such cancer in a group of

319 comma 043319,043

people. Estimate the probability of

6464

or fewer cases of such cancer in a group of

319 comma 043319,043

people. What do these results suggest about media reports that cell phones cause cancer of the brain or nervous system?
