In a study of 320,354 cell phone users, it was found that 34 developed cancer of the brain or nervous system. Assuming that cell phones have no effect, there is a 0.000142 probability of a person developing cancer of the brain or nervous system. We therefore expect about 46 cases of such cancer in a group of 320,354 people. Estimate the probability of 34 or fewer cases of such cancer in a group of 320,354 people. What do these results suggest about media reports that cell phones cause cancer of the brain or nervous system? (a) P(xs 34)= (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 correct because one would expect that less than 46 cell phone users would develop cancer and the study offers some evidence to support this. O B. The media reports appear to be incorrect because one would expect that more than 46 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 C. The media reports appear to be correct because one would expect that more than 34 cell phone users would develop cancer and the study offers some evidence to support this.

In a study of 320,354 cell phone users, it was found that 34 developed cancer of the brain or nervous system. Assuming that cell phones have no effect, there is a 0.000142 probability of a person developing cancer of the brain or nervous system. We therefore expect about 46 cases of such cancer in a group of 320,354 people. Estimate the probability of 34 or fewer cases of such cancer in a group of 320,354 people. What do these results suggest about media reports that cell phones cause cancer of the brain or nervous system? (a) P(xs 34)= H(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 correct because one would expect that less than 46 cell phone users would develop cancer and the study offers some evidence to support this O B.
