In a study of 358 comma 945 cell phone users, it was found that 66 developed cancer of the brain or nervous system. Assuming that cell phones have no effect, there is a 0.000193 probability of a person developing cancer of the brain or nervous system. We therefore expect about 70 cases of such cancer in a group of 358 comma 945 people. Estimate the probability of 66 or fewer cases of such cancer in a group of 358 comma 945 people. What do these results suggest about media reports that cell phones cause cancer of the brain or nervous system?
