In a study of 205,590 cell phone users, it was found that 38 developed cancer of the brain or nervous system. Assuming that cell phones have no effect, there is 0.000236 probability of a person developing cancer of the brain or nervous system. We therefore expect about 49 cases of such cancer in a group of 205,590 people. Estimate the probability of 38 or fewer cases of such cancer in a group of 205,590 people. What do these results suggest about media reports that cell phone cause cancer of the brain or nervous system. (a) P(x<=38)= (Round to four decimal places as needed)
(b) What does the result from part (a) suggest about the media reports?
A. The media reports appear to be correct because one would expect that more than 38 cell phone users would develop cancer and the study offers some evidence to support this.
B. The media reports appear to be correct because one would expect that less than 49 cell phone users would develop cancer and the study offers some evidence to support this.
C. The media reports appear to be incorrect because one would expect that more than 49 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.
