In a study of 298 comma 049 cell phone users, it was found that 132 developed cancer of the brain or nervous system. assuming that cell phones have no effect, there is a 0.000485 probability of a person developing cancer of the brain or nervous system. we therefore expect about 145 cases of such cancer in a group of 298 comma 049 people. estimate the probability of 132 or fewer cases of such cancer in a group of 298 comma 049 people. what do these results suggest about media reports that cell phones cause cancer of the brain or nervous system?
