Question

A study of 420,005 cell phone users found that 135 of them developed cancer of the brain or nervous system. Prior to this study of cell phone use, the rate of such cancer was found to be 0.0331% for those not using cell phones. Complete parts (a) and (b). a. Use the sample data to construct a 95% confidence interval estimate of the percentage of cell phone users who develop cancer of the brain or nervous system.

In a study of 452,318 cell phone users, it was found that 71
developed cancer of the brain or nervous system. Assuming that cell
phones have no effect, there is a 0.000208 probability of a person
developing cancer of the brain or nervous system. We therefore
expect about 95 cases of such cancer in a group of 452,318 people.

In a study of 420,102 cell phone users, 135 subjects developed
cancer of the brain or nervous system. Test the claim of a somewhat
common belief that such cancers are affected by cell phone use.
That is, test the claim that cell phone users develop cancer of
the brain or nervous system at a rate that is different from the
rate of 0.0340% for people who do not use cell phones. Because
this issue has such great importance, use a...
