In a study of 206,023 cell phone users, it was found that 32 developed cancer of the brain or nervous system. Assuming that cell phones have no effect, there is a 0.000199 probability of a person developing cancer of the brain or nervous system. We therefore expect about 41 cases of such cancer in a group of 206,023 people. Estimate the probability of 32 or fewer cases of such cancer in a group of 206,023 people. What do these results suggest about media reports that cell phones cause cancer of the brain or nervous system? (a) P(xs 32) = (Round to four decimal places as needed.)
