In a study of 274 947 cell phone users it was found that 95 developed cancer of the brain or nervous system Assuming that cell phones have no effect there is a 0 000432 probability of a person developing cancer of the brain or nervous system We therefore expect about 119 cases of such cancer in a group of 274 947 people Estimate the probability of 95 or fewer cases of such cancer in a group of 274 947 people What do these results suggest about media reports that cell phones cause cancer of the brain or nervous system a P x 95 Round to four decimal places as needed
