In a study of 349,212 cell phone users, it was found that 26 developed cancer of the brain of hervouS systel 0.000109 probability of a person developing cancer of the brain or nervous system. We therefore expect about 39 cases of such cancer in a group of 349,212 people. Estimate the probability of 26 or fewer cases of such cancer in a group of 349,212 people. What do these results suggest about media reports that cell phones cause cancer of the brain or nervous system? (a) P(xs 26) = (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 more than 26 cell phone users would develop cancer and the study offers significant evidence to support this. O B. The media reports appear to be incorrect because one would expect that more than 39 cell phone users would develop cancer. In fact, the study may offer significant evidence to suggest that cell phone use decreases the probability of developing cancer. OC. The media reports appear to be correct because one would expect that less than 39 cell phone users would develop cancer and the study offers significant evidence to support this.

Question
In a study of 349,212 cell phone users, it was found that 26 developed cancer of the brain or nervous system. Assuming that cell phones have no effect, there is a 0.000109 probability of a person developing cancer of the brain or nervous system. We therefore expect about 39 cases of such cancer in a group of 349,212 people. Estimate the probability of 26 or fewer cases of such cancer in a group of 349,212 people. What do these results suggest about media reports that cell phones cause cancer of the brain or nervous system? (a) P(xs 26) = (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 more than 26 cell phone users would develop cancer and the study offers significant evidence to support this. B. The media reports appear to be incorrect because one would expect that more than 39 cell phone users would develop cancer. In fact, the study may offer significant 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 less than 39 cell phone users would develop cancer and the study offers significant evidence to support this.
