In a study of 251,402 cell phone users, it was found that 78 developed cancer of the brain or nervous system. Assuming that cell phones have no effect, there is a 0.000327 probability of a person developing cancer of the brain or nervous system. We therefore expect about 83 cases of such cancer in a group of 251,402 people. Estimate the probability of 78 or fewer cases of such cancer in a group of 251,402 people. What do these results suggest about media reports that cell phones cause cancer of the brain or nervous system? (a) P(xs78) = (Round to four decimal places as needed.) (b) What does the result from part (a) suggest about the media reports? O A. The media reports appear to be incorrect because one would expect that more than 83 cell phone users would develop cancer. In fact, the study may offer some evidence to suggest that cell phone use decreases the probability of developing cancer. O B. The media reports appear to be correct because one would expect that less than 83 cell phone users would develop cancer and the study offers some evidence to support this. O C. The media reports appear to be correct because one would expect that more than 78 cell phone users would develop cancer and the study offers some evidence to support this.
