In a study of 321 comma 156 cell phone users, it was found that 103 developed cancer of the brain or nervous system. Assuming that cell phones have no effect, there is a 0.000332 probability of a person developing cancer of the brain or nervous system. We therefore expect about 107 cases of such cancer in a group of 321 comma 156 people. Estimate the probability of 103 or fewer cases of such cancer in a group of 321 comma 156 people. What do these results suggest about media reports that cell phones cause cancer of the brain or nervous system? g
